[0036] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0037] The following is for reference. Figures 1-4 The present invention describes a terminal structure 100 according to an embodiment of the present invention. The terminal structure 100 is disposed on the outer surface of a battery 1000, which can be used in a vehicle, such as a new energy vehicle.

[0038] As shown in the figure Figure 3 and Figure 4As shown, the pole structure 100 according to this utility model includes: pole 10 and fuse assembly 20. The pole 10 is provided with a first electrical connection part 11. The fuse assembly 20 is provided on the pole 10 and electrically connected to the pole 10. The fuse assembly 20 is provided with a second electrical connection part 21. The first electrical connection part 11 and the second electrical connection part 21 are spaced apart. The first electrical connection part 11 and the second electrical connection part 21 are used to connect different electrical connectors.

[0039] It is understandable that the terminal post 10 and the fuse assembly 20 constitute the main body of the terminal post structure 100. The fuse assembly 20 is disposed in the terminal post 10. When the battery 1000 is not jump-started, the terminal post 10 can protect the fuse assembly 20, and the fuse assembly 20 does not affect the normal operation of the battery 1000. The terminal post 10 is provided with a first electrical connection part 11, and the fuse assembly 20 is provided with a second electrical connection part 21. The first electrical connection part 11 is connected to the current inside the battery 1000, and the second electrical connection part 21 is connected to the jump-start electrical connection. Moreover, the first electrical connection part 11 and the second electrical connection part 21 are spaced apart, so that the first electrical connection part 11 and the second electrical connection part 21 do not interfere with each other. When the vehicle is not depleted, the second electrical connection part 21 is not connected to the external electrical connection of the battery 1000. When the battery is connected, the current in the battery 1000 flows only internally. When the vehicle is out of power, the external electrical connector of the battery 1000 connects to the second electrical connector. At this time, the current from the external electrical connector of the battery 1000 flows into the battery 1000 through the fuse assembly 20, thereby activating the current inside the battery 1000. If a 24V electrical connector is used to jump-start the 12V battery 1000, the fuse assembly 20 will melt due to the large voltage difference between the inside and outside of the battery 1000. At this time, the current from the outside of the battery 1000 no longer flows into the battery 1000. This can protect the battery 1000 from damage by large currents and prevent safety incidents such as leakage, smoke, and fire. This can improve the reliability of the battery 1000 and the safety of the vehicle.

[0040] For example, when the battery 1000 is working normally, the fuse component 20 is located inside the terminal 10. 12V is the power supply voltage of the vehicle's low-voltage system. The battery 1000 cannot be disconnected from the power supply at will during vehicle operation (except when the power is completely depleted). When the battery 1000 is depleted, if a 24V electrical connector is used to jump-start the 12V battery 1000, the fuse component 20 will blow. After the fuse blows, only the fuse component 20 needs to be replaced. Other components of the battery 1000 do not need to be replaced. This can reduce the cost of the battery 1000 and improve the versatility of the fuse component 20.

[0041] Therefore, by electrically connecting the fuse assembly 20 to the terminal post 10, with a first electrical connection portion 11 on the terminal post 10 and a second electrical connection portion 21 on the fuse assembly 20, and with the first and second electrical connection portions 11 and 21 spaced apart and connected to different electrical connectors, current can be transferred to the battery 1000 through the first and second electrical connection portions 11 and 21 during jump-starting. When the current is overloaded, the fuse assembly 20 melts, preventing current from entering the battery 1000, thus protecting the battery 1000 from damage by excessive current and preventing safety incidents such as leakage, smoke, and fire. This improves the reliability of the battery 1000 and the safety of the vehicle.

[0042] Among them, such as Figure 3 and Figure 4 As shown, the fuse assembly 20 includes an insulating mounting base 22 and a fuse element 23. The insulating mounting base 22 is disposed on the pole post 10, and the fuse element 23 is disposed on the insulating mounting base 22. The fuse element 23 is electrically connected to the pole post 10 and is provided with a second electrical connection part 21. The second electrical connection part 21 is spaced apart from the first electrical connection part 11 through the insulating mounting base 22.

[0043] It is understood that the insulating mounting base 22 and the fuse 23 constitute the main structure of the fuse assembly 20. The insulating mounting base 22 is disposed on the terminal post 10. The insulating mounting base 22 can limit the fuse 23, so that the fuse 23 can be disposed on the terminal post 10. Moreover, the fuse 23 is electrically connected to the terminal post 10. The fuse 23 is provided with a second electrical connection part 21. When the vehicle is jump-started, the electrical connection outside the battery 1000 flows into the battery 1000 through the second electrical connection part 21 on the fuse 23 and the terminal post 10, thereby reactivating the current in the battery 1000. The insulating mounting base 22 is located between the first electrical connection part 11 and the second electrical connection part 21, so as to block the first electrical connection part 11 and the second electrical connection part 21, thereby preventing the formation of a circuit between the first electrical connection part 11 and the second electrical connection part 21, and thus ensuring that the current of the electrical connection outside the battery 1000 flows into the battery 1000 through the fuse 23. For example, the insulating mounting base 22 is made of plastic material, which can ensure that there is a barrier between the first electrical connection 11 and the second electrical connection 21.

[0044] In addition, such as Figure 3 and Figure 4 As shown, the fuse 23 includes a fuse portion 231 and a third electrical connection portion 232. The fuse portion 231 is connected between the second electrical connection portion 21 and the third electrical connection portion 232. The third electrical connection portion 232 is electrically connected to the pole post 10. The fuse portion 231 is disposed in the insulating mounting base 22.

[0045] In other words, the fuse 231 and the third electrical connection 232 constitute the main structure of the fuse 23. The third electrical connection 232 is electrically connected to the terminal 10. This allows electrical connections outside the battery 1000 to flow into the battery 1000 sequentially through the second electrical connection 21, the fuse 231, the third electrical connection 232, the terminal 10, and the first electrical connection. When a 24V electrical connection jumpers a 12V battery 1000, due to the significant voltage difference between the inside and outside of the battery 1000, the fuse 231 melts. When the current from outside the battery 1000 no longer flows into the battery 1000, it can protect the battery 1000 from damage by large currents and prevent safety incidents such as leakage, smoke, and fire. This can improve the reliability of the battery 1000 and the safety of the vehicle. Moreover, the fuse part 231 is located inside the insulating mounting base 22, so that the insulating mounting base 22 can protect the fuse part 231, thereby extending the service life of the fuse part 231 and ensuring the performance of the fuse part 231 to melt.

[0046] Furthermore, as shown in the figure, the second electrical connection portion 21 includes a head 211 and a rod portion 212. The head 211 is disposed outside the insulating mounting base 22, and the rod portion 212 is connected between the head 211 and the fuse portion 231. The cross-sectional area of ​​the head 211 is larger than the cross-sectional area of ​​the rod portion 212, and the rod portion 212 is disposed inside the insulating mounting base 22.

[0047] It is understood that the head 211 and the rod 212 constitute the main structure of the second electrical connection part 21. The rod 212 is located between the head 211 and the fuse part 231, so that the head 211, the rod 212 and the fuse part 231 can be connected into a whole, which facilitates the replacement of the fuse assembly 20. The rod 212 is located at the edge inside the insulating mounting base 22, and the head 211 is located on the outer periphery of the insulating mounting base 22. Moreover, the cross-sectional area of ​​the head 211 is larger than the cross-sectional area of ​​the rod 212, so that the electrical connector outside the battery 1000 can contact the head 211 first, and then flow into the battery 1000 through the rod 212 and the fuse part 231, thereby ensuring the normal operation of vehicle jump-starting.

[0048] In particular, such as Figure 3 and Figure 4 As shown, the rod portion 212 is provided with one of the first flange 213 and the first groove 221, and the insulating mounting base 22 is provided with the other of the first flange 213 and the first groove 221. The first flange 213 is disposed in the first groove 221, so that the rod portion 212 and the insulating mounting base 22 can be engaged in the axial upper limit of the insulating mounting base 22.

[0049] In other words, a first flange 213 is provided on the outer periphery of the rod 212, and a first groove 221 is provided on the inner periphery of the insulating mounting base 22. The first flange 213 and the first groove 221 cooperate with each other. This not only facilitates the installation of the rod 212 and the insulating mounting base 22, but also allows the rod 212 and the insulating mounting base 22 to be axially connected, thereby facilitating the installation of the fuse assembly 20. It also facilitates the flow of current from the external electrical connector of the battery 1000 into the battery 1000 through the fuse assembly 20.

[0050] Optionally, such as Figure 4 As shown, the fuse 231 is constructed in a sheet-like shape, and the third electrical connection 232 is constructed in a sheet-like or block-like shape. This arrangement not only ensures the ability of the fuse 231 and the third electrical connection 232 to conduct current, but also facilitates the manufacturing and installation of the fuse 231 and the third electrical connection 232, and saves materials for the fuse 231 and the third electrical connection 232. Furthermore, the fuse 231 and the third electrical connection 232 can be easily inserted into the insulating mounting base 22, thereby allowing the insulating mounting base 22 to protect the fuse 231 and the third electrical connection 232, and extending the service life of the fuse 23.

[0051] In particular, such as Figure 3 and Figure 4 As shown, the fuse section 231 is provided with a plurality of spaced through holes 233. This arrangement not only saves the manufacturing material of the fuse section 231 and ensures the conductivity of the fuse section 231, but also facilitates the fuse section 231 to fuse, so that the operator can design the fusing current that the fuse section 231 can withstand based on the actual current that the battery 1000 can withstand.

[0052] In addition, such as Figure 3 As shown, the insulating mounting base 22 is provided with a second groove 222, and the edge of the third electrical connection part 232 is disposed in the second groove 222, so that the third electrical connection part 232 and the insulating mounting base 22 can be engaged in the axial upper limit of the insulating mounting base 22.

[0053] It is understood that the inner circumference of the insulating mounting base 22 is provided with a second groove 222, and the second groove 222 and the first groove 221 are spaced apart. The edge of the third electrical connection part 232 and the first groove 221 cooperate with each other. This not only facilitates the installation of the third electrical connection part 232 and the insulating mounting base 22, but also allows the third electrical connection part 232 and the insulating mounting base 22 to be axially connected, thereby facilitating the installation of the fuse assembly 20, and also facilitating the flow of current from the external electrical connection of the battery 1000 into the battery 1000 through the fuse assembly 20.

[0054] In addition, such as Figure 4As shown, the pole post 10 is provided with a mounting groove 12, and the insulating mounting base 22 includes: a first mounting part 223 and a second mounting part 224. The first mounting part 223 is disposed in the mounting groove 12, the fuse part 231 and the third electrical connection part 232 are disposed in the first mounting part 223, the second mounting part 224 is disposed outside the mounting groove 12, the second mounting part 224 is connected to the first mounting part 223, and the second electrical connection part 21 is disposed in the second mounting part 224.

[0055] In other words, a mounting groove 12 is formed in the middle of the terminal post 10. The first mounting part 223 is inserted into the mounting groove 12. The fuse part 231 and the third electrical connection part 232 are located in the first mounting part 223. This allows the fuse part 231 and the third electrical connection part 232 to be inserted into the mounting groove 12 of the terminal post 10 along with the first mounting part 223, thereby bringing the fuse part 231 and the third electrical connection part 232 close to the inside of the battery 1000 and facilitating replacement after the fuse part 231 melts. The second mounting part 224 is connected to one end of the first mounting part 223. When the first mounting part 223 is inserted into the mounting groove 12, the second mounting part 224 protrudes from the mounting groove 12, thus placing the second mounting part 224 outside the terminal post 10. A second electrical connection part 21 is provided on the second mounting part 224. When the vehicle is not out of power, the second electrical connection part 21 is not connected to the outside of the battery 1000. When the electrical connectors are connected, the current in the battery 1000 flows only internally. When the vehicle is out of power, the external electrical connector of the battery 1000 first connects to the second electrical connector. At this time, the current flows into the battery 1000 through the fuse 231 and the third electrical connector 232, thereby activating the current inside the battery 1000. If a 24V electrical connector is used to jump-start a 12V battery 1000, the fuse 231 will melt due to the large voltage difference between the inside and outside of the battery 1000. At this time, the current outside the battery 1000 is disconnected between the second electrical connector 21 and the third electrical connector 232. This can protect the battery 1000 from damage by a large current and prevent the battery 1000 from leaking, smoking, catching fire, and other safety incidents, thereby improving the reliability of the battery 1000 and the safety of the vehicle.

[0056] Among them, such as Figure 4 As shown, the cross-sectional area of ​​the second mounting part 224 is larger than that of the first mounting part 223, and the second mounting part 224 and the top surface of the pole post 10 abut against each other in the axial direction of the insulating mounting base 22.

[0057] It is understandable that the cross-sectional area of ​​the second mounting part 224 is larger than that of the first mounting part 223. When the first mounting part 223 is inserted into the mounting groove 12, the second mounting part 224 abuts against the top surface of the pole post 10, so that the second mounting part 224 protrudes from the pole post 10. Moreover, the edge of the third electrical connection part 232 engages with the second groove 222, so that the first mounting part 223 and the pole post 10 are axially engaged, thereby enabling the second mounting part 224 and the pole post 10 to be axially engaged. The second electrical connector is provided on the second mounting part 224, which facilitates the connection of the external electrical connector of the battery 1000 to the second electrical connector first.

[0058] In addition, such as Figure 4 As shown, the first mounting part 223 is detachably disposed in the mounting groove 12, and the outer peripheral surface of the second mounting part 224 is provided with an anti-slip part 225. That is, the first mounting part 223 is detachable relative to the mounting groove 12. When the fuse part 231 is not melted, the fuse part 231 and the third electrical connection part 232 are always inside the first mounting part 223, and the first mounting part 223 is always inserted into the mounting groove 12. When the fuse part 231 melts, firstly, the first mounting part 223 is removed from the mounting groove 12, then the fuse part 231 and the third electrical connection part 232 are removed and replaced, and finally, the fuse part 231 and the third electrical connection part 224 are removed and replaced. 32 is reset in the first mounting part 223, and the first mounting part 223 is inserted into the mounting groove 12. In this way, only the fuse part 231 needs to be replaced, without replacing other parts of the pole structure 100, thereby saving costs and facilitating the installation and removal of the fuse assembly 20. The outer peripheral surface of the second mounting part 224 is provided with an anti-slip part 225, which is set in a rack shape. This makes it easy for workers to disassemble and install the insulating mounting base 22 by hand, thereby improving the assembly efficiency of the fuse assembly 20.

[0059] Among them, such as Figure 4As shown, the first mounting part 223 and the second mounting part 224 are threaded together, or the first mounting part 223 and the second mounting part 224 are bonded together, or the first mounting part 223 and the second mounting part 224 are interference fit. This arrangement allows the first mounting part 223 and the second mounting part 224 to be connected as a whole, making it easy to disassemble the first mounting part 223 relative to the mounting groove 12. When the fuse part 231 is not melted, the second mounting part 224 protrudes from the terminal post 10, and the fuse part 231 and the third electrical connection part 232 are always inside the first mounting part 223. The first mounting part 223 is also always inserted into the mounting groove 12. When the fuse part 231 melts, the first mounting part 223 is first removed from the mounting groove 12, and then the fuse part 231 and the third electrical connection part 232 are removed and replaced. Finally, the fuse part 231 and the third electrical connection part 232 are reset in the first mounting part 223, and the first mounting part 223 is reinserted into the mounting groove 12. The second mounting part 224 protrudes from the terminal post 10 again, making it easier for the external electrical connectors of the battery 1000 to contact the second mounting part 224 first, thereby ensuring the convenience of vehicle jump-starting.

[0060] In addition, such as Figure 3 and Figure 4 As shown, the first electrical connection part 11 is constructed as the outer peripheral surface of the pole 10, so that the first electrical connection part 11 can connect to other electrical connectors, thereby ensuring that a circuit is formed between the pole 10 and the battery 1000, and thus ensuring the normal operation of the battery 1000.

[0061] In addition, such as Figure 3 and Figure 4 As shown, the pole structure 100 also includes an elastic conductive element 30, which is disposed between the fuse assembly 20 and the pole 10, thereby electrically connecting the fuse assembly 20 and the pole 10.

[0062] Understandably, the elastic conductive element 30 is located between the fuse assembly 20 and the terminal 10. This arrangement allows current from the external electrical connections of the battery 1000 to flow sequentially through the fuse assembly 20, the elastic conductive element 30, and the terminal 10 into the battery 1000, thus ensuring jump-start capability. Furthermore, the elastic conductive element 30 can limit the movement of the fuse assembly 20, facilitating its installation and removal, and also provides axial restraint between the fuse assembly 20 and the terminal 10, ensuring current flow. For example, the elastic conductive element 30 can be a coil spring or a disc spring, which not only facilitates installation and removal and ensures current flow but also saves costs.

[0063] In addition, the fuse assembly 20 is provided with a third electrical connection part 232, and the pole post 10 is provided with a fourth electrical connection part. The third electrical connection part 232 and the fourth electrical connection part are in surface contact, thereby electrically connecting the fuse assembly 20 and the pole post 10.

[0064] In other words, a third electrical connection part 232 is provided at the bottom of the fuse assembly 20, and a fourth electrical connection part is provided on the terminal post 10. The third electrical connection part 232 and the fourth electrical connection part are in surface contact, so that current can pass through the third electrical connection part 232 and the fourth electrical connection part, thereby making the fuse assembly 20 and the terminal post 10 electrically connected. This ensures that the current of the electrical connection parts outside the battery 1000 flows into the battery 1000 through the fuse assembly 20 and the terminal post 10, thus ensuring the successful completion of jump-start.

[0065] Specifically, when the vehicle is under normal operating conditions, the first electrical connection 11 on the terminal 10 is connected to the vehicle's wiring harness and forms a circuit, bypassing the fuse assembly 20. This ensures normal vehicle operation. Even when the vehicle experiences high-current discharge or charging, the fuse assembly 20 will not blow as long as the safety of the battery cells in the battery 1000 is guaranteed. When the safety threshold of the battery 1000 management system is exceeded, the battery 1000 management system will actively disconnect the relay in the circuit. When the vehicle is low on power, jump-starting the battery 1000 is required. The external electrical connector of battery 1000 contacts the fuse assembly 20 to form a contact circuit. If the current of the external electrical connector of battery 1000 is high or the current inside battery 1000 is low, a large charging current is formed in the circuit. If this current exceeds the maximum allowable current in the design, the fuse 23 will melt, and the charging circuit will be disconnected, thus ensuring the safety of battery 1000. After the fuse 23 melts, the vehicle needs to replace the fuse assembly 20 at a service shop, which ensures the economy and maintainability of the fuse assembly 20.

[0066] like Figure 1 and Figure 2As shown, the battery 1000 according to this utility model includes: the terminal structure 100 of the above embodiment. A fuse assembly 20 is disposed in the terminal 10. When the battery 1000 is not jump-started, the terminal 10 can protect the fuse assembly 20, and the fuse assembly 20 does not affect the normal operation of the battery 1000. A first electrical connection portion 11 is provided on the terminal 10, and a second electrical connection portion 21 is provided on the fuse assembly 20. The first electrical connection portion 11 is connected to the current inside the battery 1000, and the second electrical connection portion 21 is connected to the jump-start electrical connector. The first electrical connection portion 11 and the second electrical connection portion 21 are spaced apart, so that the first electrical connection portion 11 and the second electrical connection portion 21 do not interfere with each other. When the vehicle is not depleted, the second electrical connection portion 21 is not connected to the external electrical connector of the battery 1000. At this time, the current of the battery 1000... The battery operates only internally. When the vehicle is out of power, the external electrical connector of the battery 1000 connects to the second electrical connector. At this time, the current flows into the battery 1000 through the fuse assembly 20, thereby activating the current inside the battery 1000. If a 24V electrical connector is used to jump-start the 12V battery 1000, the fuse assembly 20 will melt due to the large voltage difference between the inside and outside of the battery 1000. At this time, the current from the outside of the battery 1000 will no longer flow into the battery 1000. This protects the battery 1000 from damage by a large current and also prevents safety incidents such as leakage, smoke, and fire. This improves the reliability of the battery 1000 and the safety of the vehicle.

[0067] The vehicle according to this utility model includes: the battery 1000 of the above embodiment. By electrically connecting the fuse assembly 20 to the terminal post 10, the terminal post 10 is provided with a first electrical connection portion 11, and the fuse assembly 20 is provided with a second electrical connection portion 21. The first electrical connection portion 11 and the second electrical connection portion 21 are spaced apart, and the first electrical connection portion 11 and the second electrical connection portion 21 are respectively connected to different electrical connectors. In this way, during the jump-start process, the current can be transmitted to the battery 1000 through the first electrical connection portion 11 and the second electrical connection portion 21. When the current is overloaded, the fuse assembly 20 melts, and at this time, the current can no longer enter the battery 1000, thereby protecting the battery 1000 from damage by large currents. It can also prevent the battery 1000 from leaking, smoking, catching fire, and other safety events, thereby improving the reliability of the battery 1000 and the safety of the vehicle.
