Description

Technical Field

[0001] The invention belongs to the technical field of lithium batteries for electric vehicles, and in particular relates to a high-protection lithium battery for electric vehicles. Background Art

[0002] Lithium batteries are lithium-ion batteries. The cells of lithium-ion batteries are mainly composed of positive electrode materials, negative electrode materials, separators and electrolytes. Among them, the separator is an important component of the cell. It can separate the positive and negative electrodes of the battery and has electronic insulation and ion conductivity. The performance of the separator determines the interface structure of the battery, the retention of the electrolyte and the internal resistance of the battery, which in turn affects the key characteristics of the battery such as capacity, cycle performance, and charge and discharge current density. In the actual application of lithium-ion batteries, complex charging and discharging conditions may lead to problems such as overcharging, over-discharging and overheating, which in turn cause serious safety hazards such as rapid battery performance degradation, internal short circuits and thermal runaway.

[0003] At present, when the capacity of the negative electrode of the positive electrode of the lithium battery is insufficient, the lithium atoms generated during charging cannot be inserted into the interlayer structure of the negative electrode graphite, and will be precipitated on the surface of the negative electrode to form crystals. The long-term formation of crystals in the lithium battery will cause a short circuit. At this time, the battery cell discharges rapidly, which will generate a lot of heat and burn the diaphragm. High temperature will decompose the electrolyte into gas, and the battery cell will explode when the pressure is too high. Before that, the battery will emit high-temperature heat. At present, the battery can only be supervised by the BMS battery management system, which is mainly responsible for monitoring and managing the operating status of rechargeable batteries. However, the system is expensive to use and is implemented using multi-sensor equipment. It will face the problem of sensitivity failure during use, and the lithium battery itself is not highly protective. Therefore, the current lithium batteries are still dangerous in use. There are many lithium batteries that spontaneously combust on the market. The lithium battery itself is not highly protective, which makes some people wary and uneasy about the use of lithium batteries. Summary of the invention

[0004] The purpose of the present invention is to provide a high-protection lithium battery for electric vehicles, which has the advantage that when a short circuit occurs in the battery body and may gradually explode, the pressure generated by the explosion is discharged to avoid a larger explosion in a closed situation, and at the same time, the sparks generated by the explosion of the battery body are prevented from scattering and causing greater damage to the electric vehicle; when the battery body needs to be maintained and repaired, portable disassembly and installation between the shell and the base is achieved, which increases the operating convenience of the lithium battery and reduces the time required for disassembly and installation.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: a high-protection lithium battery for electric vehicles, including a battery mechanism, the battery mechanism including a shell, a base is provided at the bottom of the shell, a battery body is provided on the top of the base, both sides of the battery body are fixedly installed with fixing plates fixedly connected to the base, both sides of the shell are provided with heat dissipation ports, a rubber ring located on the inner side of the shell is fixedly adhered to the top of the base, a heat dissipation sealing mechanism is provided on the inner side of the shell, the heat dissipation sealing mechanism includes an adjustment component, an interference component, and a sealing component, and both ends inside the base are provided with stabilizing mechanisms, and the stabilizing mechanism includes a clamping component and a stabilizing component.

[0006] By adopting the above technical solution, when the high-protection lithium battery for electric vehicles is used, when the battery body is short-circuited, the mercury will expand due to the heat change of the battery body. Thus, the adjustment component drives the interference component to drive the transmission, and the sealing component will be sealed to the battery mechanism. Through this setting, when the battery body is short-circuited and may gradually explode, the pressure generated by the explosion will be discharged to avoid a larger explosion under the closed condition, and the sparks generated by the explosion of the battery body will be avoided. The electric vehicle is more damaged. In addition, when using the high-protection lithium battery for electric vehicles, the operator first installs the battery body and the base, and then covers the shell on the top of the base. Then the operator realizes the stable connection between the base and the shell by linking the clamping component with the stabilizing component. At the same time, through the setting of the stabilizing component, when the battery body needs to be maintained and repaired, the portable disassembly and installation between the shell and the base can be realized, which increases the convenience of operation of the lithium battery and reduces the time required for disassembly and installation.

[0007] The present invention is further configured as follows: the adjustment component includes an inner shell one and an inner shell two, the inner shell one and the inner shell two are fixedly connected to each other by a connecting block one fixedly connected to the inner side of the outer shell, the inner shell one and the inner shell two are both slidably connected to the inside of a piston plate, a piston rod is fixedly installed on one side of the piston plate, and the surfaces of the two piston rods are fixedly sleeved with a spring one fixedly connected to the inside of the inner shell one and the inner shell two respectively.

[0008] By adopting the above technical solution, in the use of this structure, mercury is preferentially filled in the inner shell 1 and the inner shell 2. The inner shell 1 and the inner shell 2 will be fixedly supported by the use of the connecting block 1. The mercury will remain in a slightly expanded state at room temperature as the temperature of the battery body changes under normal use. When the battery is short-circuited, it will expand rapidly and in large volume due to the high temperature of the battery. At this time, the piston plates in the inner shell 1 and the inner shell 2 are squeezed by the expansion of mercury to achieve lateral movement, and the piston plate will drive the piston rod to move synchronously. The spring 1 is contracted in coordination with the movement of the piston plate, and the setting of the spring 1 will cooperate with the piston plate to always keep close to the mercury with constantly changing volume.

[0009] The present invention is further configured as follows: one end of the two piston rods respectively penetrates one end of inner shell one and inner shell two, one end of the piston rod is fixedly mounted with a rack one, one end of the rack one is provided with a gear one, the gear one and rack one are meshed with each other for use, and a connecting rod one is fixedly sleeved inside the gear one and is rotatably connected to the inner side of the outer shell.

[0010] With the above technical solution, the movement of the piston rod will drive the rack 1 to move, and the rack 1 will gradually achieve meshing transmission with the gear 1 after continuously moving a certain distance. During the unilateral movement of the rack 1, this movement range will be adapted to the reasonable expansion range of mercury, that is, the reasonable temperature rise of the battery. When the rack 1 continues to move and the transmission gear 1 rotates, it means that the battery has heated up to an unreasonable temperature and needs to be closed and protected later. The rotation of the gear 1 will drive the connecting rod 1 to rotate synchronously.

[0011] The present invention is further configured as follows: the interference assembly includes connecting rod 2, the number of connecting rod 2 is two and they are located at the top of connecting rod 1, one end of connecting rod 2 is fixedly sleeved with gear 2, the other ends of connecting rod 2 and connecting rod 1 are fixedly sleeved with synchronous wheels, the surfaces of the two synchronous wheels are mutually connected with a synchronous belt, the surface of gear 2 is meshed with rack 2, and a tooth block is provided on the top of rack 2.

[0012] By adopting the above technical solution, the synchronous rotation of connecting rod one and connecting rod two can be achieved through the setting of synchronous belt and synchronous wheel, wherein the rotation of connecting rod two will drive rack two to rotate, and the distance between the teeth on one side of the gear block and the teeth on one side of rack two will be the spacing range of one tooth of gear two meshing.

[0013] The present invention is further configured as follows: side panels one are fixedly installed on the tops of both sides of the second rack, side panels two are fixedly installed on both sides of the tooth block, a guide rod one is fixedly installed on the top of the first side panel and penetrates to the top of the second side panel, the guide rod one and the second side panel are slidably connected to each other, a limit block is fixedly installed on the top of the guide rod one, a spring two is sleeved on the surface of the guide rod one, and both ends of the spring two are respectively fixedly connected to the first side panel and the second side panel.

[0014] With the above technical solution, when rack 2 is continuously moved by meshing with gear 2, gear 2 meshes with one end of rack 2 to achieve meshing with tooth block, and the movement of spring 2 and guide rod 2 will make the tooth block move laterally in meshing with gear 2, and make spring 2 contract, and side plate 2 slide on the surface of guide rod 1. As the teeth on the surface of gear 2 rotate progressively, spring 2 will make the tooth block return to the initial position in the extended state, so that the tooth block cooperates with the next meshing transmission of the teeth on the surface of gear 2. This arrangement can ensure that rack 2 will not continue to move due to the expansion change of mercury when the mercury continues to heat up.

[0015] The present invention is further configured as follows: the closing component includes a sealing plate, the top of the sealing plate is fixedly installed with a connecting block 2 fixedly connected to the bottom of the rack 2, the top and bottom of both sides of the sealing plate are fixedly installed with guide rings, the inside of the guide ring is slidably connected with a guide rod 2 fixedly connected to the inner side of the outer shell, and the inside of the sealing plate is opened with a pressure relief hole, and the pressure relief hole is of inclined design.

[0016] With the above technical solution, the movement of rack 2 will drive the connection block 2 and the sealing plate to move synchronously, and the sealing plate will seal the heat dissipation port. However, in the case of a short circuit in the battery body and possible gradual explosion, the pressure relief hole will discharge the pressure generated by the explosion to avoid a larger explosion under the closed condition, and at the same time, prevent the sparks generated by the explosion of the battery body from scattering from the heat dissipation port, causing greater damage. The pressure relief hole is designed to be tilted downward, because the sparks move upward in diffusion combustion, and the pressure relief hole will prevent the sparks from leaking out of the pressure relief hole through its opening design.

[0017] The present invention is further configured as follows: the clamping assembly includes a disc one and a disc two, the insides of the disc one and the disc two are fixedly sleeved with a rod body rotatably connected to the base, one end of the two rod bodies are fixedly sleeved with a meshing gear, and the two meshing gears are staggered.

[0018] By adopting the above technical solution, the rotation of the meshing gear will drive the rod body to rotate, wherein the rotation of the rod body will respectively drive the first disk and the second disk to rotate.

[0019] The present invention is further configured as follows: arc-shaped clamping parts are fixedly installed on the surfaces of the first and second disks, an end clamping joint is fixedly installed on one end of the arc-shaped clamping part, and a clamping groove for matching the arc-shaped clamping part and the end clamping joint is provided inside the shell.

[0020] With the above technical solution, the rotation of the first and second disks will drive the arc-shaped clamping parts to rotate, and the rotation of the arc-shaped clamping parts will drive the end clamping joints to move synchronously, and the movement trend of the end clamping joints is to move around the rod body as the center of the circle. The shell is clamped with the arc-shaped clamping parts and the end clamping joints after movement through the clamping groove, so as to realize the clamping fixation of the base and the shell. In addition, in the use of the rod body, the arc-shaped clamping parts and the end clamping joints, the structure is made of high manganese steel, which has a certain anti-violence and anti-impact effect.

[0021] The present invention is further configured as follows: the stabilizing component includes a horizontal plate, the number of the horizontal plates is two, one end of the horizontal plate passes through the outside of the base and is fixedly installed with a pull ring, both ends of the top of the horizontal plate are fixedly installed with meshing teeth, and the two meshing teeth are respectively staggeredly arranged on the top of the horizontal plate and mesh with the meshing gears for use.

[0022] By adopting the above technical solution, the cross plate can be easily extracted and moved through the pull ring. When the cross plate moves, the meshing teeth will be driven to move, wherein the meshing teeth and the two adjacent meshing gears are staggered. This staggered arrangement will enable the meshing teeth to only mesh with the matching meshing gears to avoid mutual interference.

[0023] The present invention is further configured as follows: a mounting block is fixedly installed on one side of the horizontal plate, bolts are provided on both sides of the top of the base and penetrate the base to the inside of the mounting block, threaded holes are provided inside the mounting block and the base, and the threaded holes and the bolts are threadedly connected to each other.

[0024] By adopting the above technical solution, the mounting block will be installed and used in conjunction with the cross plate, wherein the operator can rotate the bolt into the threaded hole to achieve a fastened installation between the mounting plate and the base.

[0025] In summary, the present invention has the following beneficial effects:

[0026] 1. When using high-protection lithium batteries for electric vehicles, when the battery body is short-circuited, mercury will expand due to the heat change of the battery body. Thus, the adjustment component drives the interference component to drive the transmission, and the sealing component will seal the battery mechanism. Through this setting, when the battery body is short-circuited and may gradually explode, the pressure generated by the explosion will be discharged to avoid a larger explosion under the closed condition, and at the same time, the sparks generated by the explosion of the battery body will be prevented from scattering, causing greater damage to the electric vehicle;

[0027] 2. When using high-protection lithium batteries for electric vehicles, the operator should first install the battery body and the base, and then cover the shell on the top of the base. Then the operator can achieve a stable connection between the base and the shell through the linkage of the stabilizing component and the clamping component. At the same time, the setting of the stabilizing component can realize the portable disassembly and installation between the shell and the base when the battery body needs to be maintained and repaired, which increases the convenience of the lithium battery operation and reduces the time required for disassembly and installation.

[0047] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0048] Embodiment 1:

[0049] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4, Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 A high-protection lithium battery for electric vehicles includes a battery mechanism 1, the battery mechanism 1 includes a shell 101, a base 102 is provided at the bottom of the shell 101, a battery body 104 is provided on the top of the base 102, both sides of the battery body 104 are fixedly installed with fixing plates 105 fixedly connected to the base 102, both sides of the shell 101 are opened with heat dissipation ports 103, a rubber ring 106 located on the inner side of the shell 101 is fixedly adhered to the top of the base 102, a heat dissipation sealing mechanism 2 is provided on the inner side of the shell 101, and the heat dissipation sealing mechanism 2 includes an adjustment component 201, an interference component 202, and a sealing component 203. When the high-protection lithium battery for electric vehicles is used, when a short circuit occurs in the battery body 104, mercury will expand due to the heat change of the battery body 104. Thereby, the adjusting component 201 drives the interference component 202 for transmission driving, and the sealing component 203 seals the battery mechanism 1. Through this arrangement, when the battery body 104 is short-circuited and may gradually explode, the pressure generated by the explosion can be discharged to avoid a larger explosion under the closed condition, and at the same time, the sparks generated by the explosion of the battery body 104 can be prevented from scattering, causing greater damage to the electric vehicle.

[0050] refer to Figure 4 , Figure 5 , Figure 6The regulating assembly 201 includes an inner shell 1 2011 and an inner shell 2 2012, wherein the inner shell 1 2011 and the inner shell 2 2012 are fixedly connected to each other with a connecting block 1 2019 fixedly connected to the inner side of the outer shell 101, and the inner shell 1 2011 and the inner shell 2 2012 are both slidably connected with a piston plate 2013, and a piston rod 2014 is fixedly installed on one side of the piston plate 2013, and the surfaces of the two piston rods 2014 are fixedly sleeved with springs 1 2015 fixedly connected to the inner shell 1 2011 and the inner shell 2 2012 respectively. In the use of this structure, mercury is preferably filled in the inner shell 1 2011 and the inner shell 2 2012. The inner shell 1 2011 and the inner shell 2 2012 will be fixedly supported by the use of the connecting block 1 2019. The mercury will maintain a slight expansion state at room temperature as the temperature of the battery body 104 changes under normal use. When the battery is short-circuited, it will expand rapidly and in large volume due to the high temperature of the battery. At this time, the piston plates 2013 in the inner shell 1 2011 and the inner shell 2 2012 are squeezed by the expansion of mercury to achieve lateral movement, and the piston plate 2013 will drive the piston rod 2014 to move synchronously. The spring 1 2015 is contracted in coordination with the movement of the piston plate 2013. The spring 1 2015 is arranged to cooperate with the piston plate 2013 to always keep close to the mercury with a constantly changing volume.

[0051] refer to Figure 4 , Figure 5 , Figure 7 , one end of the two piston rods 2014 penetrates one end of the inner shell 1 2011 and the inner shell 2 2012 respectively, a rack 1 2016 is fixedly installed at one end of the piston rod 2014, a gear 1 2017 is provided at one end of the rack 1 2016, gear 1 2017 and rack 1 2016 are meshed with each other, a connecting rod 1 2018 is fixedly sleeved inside the gear 1 2017 and is rotatably connected to the inner side of the outer shell 101, the movement of the piston rod 2014 will drive the rack 1 2016 to move, wherein the rack 1 2016 can gradually achieve meshing transmission to the gear 1 2017 after continuously moving one end distance. In the process of unilateral movement of the rack 1 2016, this movement range will be adapted to the reasonable expansion range of mercury, that is, the reasonable temperature rise of the battery. When the rack 1 2016 continues to move and drives the gear 1 2017 to rotate, it means that the battery is heated to an unreasonable temperature, and a subsequent closed protection link is required. The rotation of gear 1 2017 will drive connecting rod 1 2018 to rotate synchronously.

[0052] refer to Figure 4 , Figure 5 , Figure 8The interference assembly 202 includes a second connecting rod 2021. There are two second connecting rods 2021 and they are located at the top of the first connecting rod 2018. One end of the second connecting rod 2021 is fixedly sleeved with a second gear 2022. The other ends of the second connecting rod 2021 and the first connecting rod 2018 are fixedly sleeved with a synchronous wheel 2023. The surfaces of the two synchronous wheels 2023 are mutually connected with a synchronous belt 2024 for transmission. The surface of the second gear 2022 is meshed with a rack 2025. A tooth block 2026 is provided on the top of the rack 2025. The synchronous rotation of the first connecting rod 2018 and the second connecting rod 2021 is achieved through the arrangement of the synchronous belt 2024 and the synchronous wheel 2023. When the second connecting rod 2021 rotates, the rack 2025 will be driven to rotate. The distance between the teeth on one side of the tooth block 2026 and the teeth on one side of the rack 2025 will be the spacing range of one tooth meshing with the second gear 2022.

[0053] refer to Figure 5 , Figure 8 , Fig. 9 , the tops of both sides of rack 2025 are fixedly installed with side plates 2027, the sides of tooth block 2026 are fixedly installed with side plates 2028, the tops of side plates 2027 are fixedly installed with guide rods 2029 that penetrate to the tops of side plates 2028, the guide rods 2029 and side plates 2028 are slidably connected to each other, the tops of guide rods 2029 are fixedly installed with limit blocks 20211, the surface of guide rods 2029 is sleeved with springs 20210, and the two ends of springs 20210 are respectively connected with side plates 1 The rack 2027 and the side plate 2028 are fixedly connected to each other. When the rack 2025 is continuously moved by the meshing of the gear 2022, the gear 2022 meshes with one end of the rack 2025, and the meshing of the tooth block 2026 is realized. The movement of the spring 20210 and the guide rod 2034 enables the tooth block 2026 to move horizontally in the meshing with the gear 2022, and the spring 20210 is contracted, and the side plate 2028 slides on the surface of the guide rod 1 2029. As the teeth on the surface of the gear 2022 rotate progressively, the spring 20210 in the extended state will make the tooth block 2026 return to the initial position, so that the tooth block 2026 cooperates with the next meshing transmission of the teeth on the surface of the gear 2022. Through this arrangement, when the mercury continues to heat up, the rack 2025 will not be continuously moved by the expansion change of mercury.

[0054] refer to Figure 4 , Fig.10 , Fig.11The sealing component 203 includes a sealing plate 2031, and a connecting block 2032 fixedly connected to the bottom of the rack 2025 is fixedly installed on the top of the sealing plate 2031. Guide rings 2033 are fixedly installed on the top and bottom of both sides of the sealing plate 2031. The guide rings 2033 are internally slidably connected to guide rods 2034 fixedly connected to the inner side of the shell 101. A pressure relief hole 2035 is opened inside the sealing plate 2031. The pressure relief hole 2035 is an inclined design. The movement of the rack 2025 will drive the connecting block 2032 and the sealing plate 2031 to move synchronously. The sealing plate 2031 will close the heat dissipation port 103. However, in the case that the battery body 104 is short-circuited and may gradually explode, the pressure relief hole 2035 cooperates with the pressure generated by the explosion to discharge, thereby avoiding a larger explosion in the closed state, and at the same time avoiding the sparks generated by the explosion of the battery body 104 from scattering from the heat dissipation port 103, causing greater damage. The pressure relief hole 2035 is designed to be inclined downward. The principle is that sparks move upward during diffusion combustion, and the pressure relief hole 2035 can prevent sparks from leaking out of the pressure relief hole 2035 through its opening design.

[0055] Brief description of the use process: When using a high-protection lithium battery for electric vehicles, when the battery body 104 is short-circuited, the mercury will expand due to the heat change of the battery body 104. Mercury will maintain a slight expansion state at room temperature as the temperature of the battery body 104 changes under normal use. When the battery is short-circuited, it will expand rapidly and in large volume due to the high temperature of the battery. At this time, the piston plate 213 in the inner shell 1 2011 and the inner shell 2 212 are squeezed by the expansion of mercury to achieve lateral movement. At the same time, the piston plate 213 will drive the piston rod 214 to move synchronously. Among them, the spring 1 215 is contracted in cooperation with the movement of the piston plate 213. The setting of the spring 1 215 will cooperate with the piston plate 213 to always keep close to the mercury with constantly changing volume. The movement of the piston rod 214 will drive the rack 1 216 to move, and the rack 1 216 can gradually achieve meshing transmission with the gear 1 217 after continuously moving a certain distance. During the unilateral movement of rack 1 2016, this movement range will be adapted to the reasonable expansion range of mercury, that is, the reasonable temperature rise of the battery. When rack 1 2016 continues to move and drives gear 1 2017 to rotate, it means that the battery has heated up to an unreasonable temperature and needs to be closed and protected later. The rotation of gear 1 2017 will drive connecting rod 1 2018 to rotate synchronously. The synchronous rotation of connecting rod 1 2018 and connecting rod 2 2021 will be achieved through the setting of synchronous belt 2024 and synchronous wheel 2023. During the rotation of connecting rod 2 2021, rack 2 2025 will be driven to rotate, and the distance between the teeth on one side of tooth block 2026 and the teeth on one side of rack 2 2025 will be the spacing range of one tooth of gear 2 2022 meshing. When the rack 2025 is continuously moved by the meshing of the gear 2022, the gear 2022 meshes with one end of the rack 2025, and the meshing of the tooth block 2026 is realized. The movement of the spring 20210 and the guide rod 2034 causes the tooth block 2026 to move laterally in the meshing with the gear 2022, and causes the spring 20210 to be contracted, and the side plate 2028 to slide on the surface of the guide rod 1 2029. As the teeth on the surface of the gear 2022 rotate progressively, the spring 20210 in the extended state causes the tooth block 2026 to return to the initial position, so that the tooth block 2026 cooperates with the next meshing transmission of the teeth on the surface of the gear 2022. This arrangement allows the rack 2025 to continue to move without being affected by the expansion of mercury when the mercury continues to heat up. The movement of the second rack 2025 will drive the second connecting block 2032 and the sealing plate 2031 to move synchronously, and the sealing plate 2031 will seal the heat dissipation port 103 .This arrangement will enable the pressure relief hole 2035 to discharge the pressure generated by the explosion when the battery body 104 is short-circuited and may gradually explode, thereby avoiding a larger explosion in a closed state and preventing sparks generated by the explosion of the battery body 104 from scattering from the heat dissipation port 103 and causing greater damage. The pressure relief hole 2035 is designed to be tilted downward, based on the principle that sparks move upward during diffusion combustion, and the pressure relief hole 2035 will prevent sparks from leaking out of the pressure relief hole 2035 through its open hole design.
