Abstract
Description
Technical Field
[0001] This application relates to the field of battery safety technology, and in particular to an electric vehicle battery. Background Technology
[0002] With the rapid development of industries such as food delivery and errand running, the demand for battery-swapping electric bicycles has surged, leading to a corresponding expansion in the deployment of battery swapping stations. In existing battery swapping stations, electric bicycle batteries are placed in the battery compartment with the charging end facing inwards and the discharge socket and operating handle facing outwards. During charging, the charging end of the electric bicycle battery contacts the receiving electrode inside the compartment to achieve charging; after the user removes the battery, they need to connect the wiring harness plug to the outward-facing discharge socket to power the electric bicycle.
[0003] However, the metal electrode plates of the discharge socket are directly exposed to the external environment. During the charging or storage of electric vehicle batteries, accidental contact by personnel or intrusion of foreign objects (such as metal objects) may cause short circuits between the electrodes, leading to battery overheating, arc discharge, or even fire, posing a significant safety hazard. Utility Model Content
[0004] The main purpose of this application is to provide an electric vehicle battery that aims to improve the problem that the metal electrode plates of the discharge socket of existing electric vehicle batteries are directly exposed to the external environment, making them easy to be accidentally touched by people or invaded by foreign objects (such as metal objects), which can lead to short circuits between the electrodes.
[0005] To achieve the above objectives, the electric vehicle battery proposed in this application is used in a battery swapping cabinet. The electric vehicle battery includes a battery body, a discharge socket, and a socket locking device. The discharge socket is fixedly installed on the battery body, and the socket locking device is installed on the discharge socket.
[0006] The socket locking device includes a movably disposed locking plate, which has a first position that blocks the discharge socket and a second position that avoids the discharge socket. Under the action of external force, the locking plate can switch between the first position and the second position.
[0007] The socket locking device is also configured to restrict the movement of the locking plate and lock the locking plate in the first position when the electric vehicle battery is placed in the battery compartment of the battery swapping cabinet.
[0008] In some embodiments of this application, the locking plate includes a first plate, a second plate, and a connecting portion fixedly connected between the first plate and the second plate. The connecting portion is rotatably mounted on the discharge socket. When the electric vehicle battery is placed in the battery compartment, the first plate abuts against the wall of the battery compartment to restrict the rotation of the second plate.
[0009] In some embodiments of this application, a first torsion spring is provided between the connecting part and the discharge socket to elastically drive the second plate to remain in the first position.
[0010] In some embodiments of this application, the discharge socket is provided with a connecting ear on its lower side in the vertical direction, and the connecting part is rotatably connected to the connecting ear.
[0011] In some embodiments of this application, the socket locking device further includes a mounting base and a flip cover. The mounting base is fixedly disposed on the discharge socket, and the locking plate is rotatably mounted on the mounting base. The flip cover is rotatably mounted on the mounting base and has an abutment portion. When the electric vehicle battery is placed in the battery compartment of the battery swapping cabinet, the flip cover abuts against the wall of the battery compartment, and the abutment portion abuts against the locking plate to restrict the rotation of the locking plate.
[0012] In some embodiments of this application, the flip cover includes a drive plate, a connecting plate, and an abutment plate. The drive plate and the abutment plate are arranged parallel to each other. One side of the drive plate is rotatably mounted on the mounting base, and the other side of the drive plate is connected to the connecting plate. The connecting plate is also connected to the abutment plate, and the abutment plate is provided with the abutment portion.
[0013] In some embodiments of this application, the discharge socket has a mounting surface, and the mounting surface is recessed with a socket.
[0014] The socket locking device also includes a mounting base, which is fixedly mounted on the discharge socket. The locking plate is rotatably mounted on one side of the mounting base. The axis of rotation of the locking plate is perpendicular to the mounting plane and located on one side of the socket in the horizontal direction. When the electric vehicle battery is placed in the battery compartment of the battery swapping cabinet, both sides of the locking plate abut against the compartment wall of the battery compartment and the battery body, respectively, to restrict the rotation of the locking plate.
[0015] In some embodiments of this application, the locking plate is further provided with a locking rod extending along its length;
[0016] The socket locking device further includes a locking member, which is rotatably mounted on the side of the mounting base away from the locking plate, and the axis of rotation of the locking member is parallel to the mounting plane. The locking member is provided with a sliding part and a locking part. When the electric vehicle battery is placed in the battery compartment of the battery swapping cabinet, the sliding part cooperates with the compartment wall of the battery compartment, so that the locking part cooperates with the locking rod to lock the locking rod to the locking member.
[0017] In some embodiments of this application, a second torsion spring is further provided between the locking member and the mounting base to elastically drive the locking member to keep the locking part engaged with the locking rod.
[0018] In some embodiments of this application, one end of the locking member is rotatably mounted on the mounting base, and the other end of the locking member is movably provided with the locking part.
[0019] The electric vehicle battery provided in this embodiment, through the aforementioned structural configuration, allows for the following: When the electric vehicle battery is placed in the battery compartment of the battery swapping cabinet for charging or storage, the locking plate is locked in the first position by a socket locking device, protecting the power socket. When the electric vehicle battery is removed from the battery swapping cabinet for use, the locking plate is switched to the second position to avoid the discharge socket's socket hole, and then a wiring harness plug is used to connect to the outward-facing discharge socket to supply power to the electric bicycle. In this way, during the charging or storage of the electric vehicle battery, the locking plate can block the discharge socket's socket hole, preventing personnel and foreign objects from contacting the electrodes inside the socket, thereby avoiding short circuits between electrodes and effectively preventing battery overheating, arc discharge, and fire, eliminating safety hazards. Furthermore, since the socket locking device is also configured to restrict the movement of the locking plate when the electric vehicle battery is placed in the battery compartment of the battery swapping cabinet, unauthorized personnel can also release the restriction on the locking plate.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features.

[0039] like Figure 1 , Figure 4 , Figure 7 as well as Figure 10 As shown, in the battery swapping cabinet 1000, the electric vehicle battery 100 is placed in the battery compartment 200 with the charging end facing inward and the discharge socket 20 and operating handle facing outward. During charging, the charging end of the electric vehicle battery 100 contacts the receiving electrode inside the compartment to achieve charging; after the user takes out the battery, the wiring harness plug needs to be connected to the outward-facing discharge socket 20 to supply power to the electric bicycle.
[0040] The embodiments of this application propose an electric vehicle battery 100, which is applied to a battery swapping cabinet 1000. Please refer to the following: Figures 1 to 12 The electric vehicle battery 100 includes a battery body 10, a discharge socket 20, and a socket locking device 30. The discharge socket 20 is fixedly installed on the battery body 10. The battery body 10 typically includes battery cells, an insulating shell, and electrical components for controlling the release or storage of electrical energy. The battery cells and electrical components are installed inside the insulating shell, which has holes for installing the discharge socket 20. The electrode plates of the discharge socket 20 are connected to the battery cell wires via electrical components. The discharge socket 20 is typically fixed to the insulating shell using screws. The socket locking device 30 is installed on the discharge socket 20. The socket locking device 30 can also be fixedly installed on the discharge socket 20 using the aforementioned screws, or it can be movably installed on the discharge socket 20. There are various other ways to install the socket locking device 30 on the discharge socket 20, which will not be described in detail here.
[0041] The socket locking device 30 includes a movably disposed locking plate 31. The locking plate 31 has a first position that blocks the discharge socket 20 and a second position that avoids the discharge socket 20. Under the action of external force, the locking plate 31 can switch between the first position and the second position.
[0042] It is understood that the main function of the locking plate 31 in this application is to block the socket 23 of the discharge socket 20, thereby preventing personnel or foreign objects from contacting the electrodes inside the socket 23. Therefore, the locking plate 31 is usually made of insulating material, such as plastic. Considering that the locking plate 31 may need to withstand external impacts, it is preferable that the locking plate 31 is made of hard plastic.
[0043] The locking plate 31 in this activity can be directly and movably installed on the aforementioned discharge socket 20, or it can be other components movably installed on the socket locking device 30; no specific limitation is made here. The locking plate 31 can switch between a first position and a second position under the action of an external force. This external force can originate from the user, from an elastic element (torsion spring), from other components of the socket locking device 30, or even from the weight of the locking plate 31 itself. Furthermore, the external forces driving the locking plate 31 to switch from the first position to the second position and from the second position to the first position can be different or the same. For example, in some examples, both the external forces driving the locking plate 31 to switch from the first position to the second position and from the second position to the first position originate from the user. In other examples, the external force driving the locking plate 31 to switch from the first position to the second position originates from the user, while the external force driving the locking plate 31 to switch from the second position to the first position originates from the elastic element.
[0044] The socket locking device 30 is also configured to restrict the movement of the locking plate 31 and lock the locking plate 31 in a first position when the electric vehicle battery 100 is placed in the battery compartment 200 of the battery swapping cabinet 1000. That is, when the electric vehicle battery 100 is placed in the battery swapping compartment, the socket locking device 30 can cooperate with the battery compartment 200 and / or the electric vehicle battery 100 to restrict the movement of the locking plate 31, so that the locking plate 31 cannot switch between the second position and the first position, thereby locking the locking plate 31 in the first position, keeping the discharge socket 20 blocked, and achieving protection.
[0045] Specifically, the locking plate 31 of the socket locking device 30 may be configured to restrict the movement of the locking plate 31 when the electric vehicle battery 100 is placed in the battery compartment 200 of the battery swapping cabinet 1000, that is, the locking plate 31 itself cooperates with the battery compartment 200 and / or the electric vehicle battery 100 to restrict the movement of the locking plate 31 itself; or other components of the socket locking device 30 may be configured to restrict the movement of the locking plate 31 when the electric vehicle battery 100 is placed in the battery compartment 200 of the battery swapping cabinet 1000.
[0046] It should be noted that after the electric vehicle battery 100 is removed from the battery swapping cabinet 1000, the socket locking device 30 disengages from the battery compartment 200 and / or the electric vehicle battery 100. This can be done by immediately releasing the restriction on the locking plate 31, or by manually operating the socket locking device 30 to release the restriction on the locking plate 31.
[0047] The electric vehicle battery 100 provided in this embodiment, through the above-described structural configuration, allows for the following: When the electric vehicle battery 100 is placed in the battery compartment 200 of the battery swapping cabinet 1000 for charging or storage, the locking plate 31 is locked in the first position by the socket locking device 30, thus protecting the power socket. When the electric vehicle battery 100 is removed from the battery swapping cabinet 1000 for use, the locking plate 31 is switched to the second position to avoid the socket 23 of the discharge socket 20, and then a wiring harness plug is used to connect to the outward-facing discharge socket 20 to supply power to the electric bicycle. In this way, during the charging or storage of the electric vehicle battery 100, the locking plate 31 can block the socket 23 of the discharge socket 20, preventing personnel and foreign objects from contacting the electrodes inside the socket 23, thereby avoiding short circuits between electrodes, effectively preventing battery overheating and arc discharge fires, and eliminating safety hazards. In addition, since the socket locking device 30 is also configured to restrict the movement of the locking plate 31 when the electric vehicle battery 100 is placed in the battery compartment 200 of the battery swapping cabinet 1000, unauthorized personnel can also release the restriction on the locking plate 31.
[0048] In some examples, such as Figures 1 to 3 As shown, the locking plate 31 includes a first plate 311, a second plate 312, and a connecting part 313 fixedly connected between the first plate 311 and the second plate 312. The connecting part 313 is rotatably mounted on the discharge socket 20. When the electric vehicle battery 100 is placed in the battery compartment 200, the first plate 311 abuts against the wall of the battery compartment 200 to restrict the rotation of the second plate 312. The included angle between the first plate 311 and the second plate 312 is usually an obtuse angle.
[0049] It should be emphasized that the discharge socket 20 of the electric vehicle battery 100 is located on the lower side of the battery body 10. When the electric vehicle battery 100 is placed in the battery compartment 200, the discharge socket 20 is adjacent to the compartment wall of the battery compartment 200, such as... Figure 1 As shown. In this embodiment, the connecting part 313 is rotatably mounted on the lower side of the discharge socket 20, specifically, located below the socket 23 in the vertical direction.
[0050] In this embodiment, through the above-described structural configuration, the first plate 311 and the second plate 312 are fixedly connected by the connecting part 313, forming an integral locking plate 31. That is, when the first plate 311 is subjected to force, it will affect the second plate 312, and similarly, when the second plate 312 is subjected to force, it will also affect the first plate 311. After the electric vehicle battery 100 is placed in the battery compartment 200 of the battery swapping cabinet 1000, the entire assembly is subject to the interaction between the discharge socket 20 and the battery compartment 200, and the entire assembly cannot rotate. That is, the first plate 311 and the second plate 312 are restricted from rotating, and the second plate 312 will tightly block the socket 23. After the electric vehicle battery 100 is removed from the battery compartment 200, the first plate 311 no longer cooperates with the battery compartment 200, and the first plate 311 and the second plate 312 can move under the action of external force. This ensures that the electric vehicle battery 100 can be protected by the second plate 312 within the battery compartment 200, thereby improving the safety of the electric vehicle battery 100.
[0051] In some examples, such as Figures 1 to 3 As shown, a first torsion spring 32 is also provided between the connecting part 313 and the discharge socket 20 to elastically drive the second plate 312 to remain in the first position. With this configuration, when the electric vehicle battery 100 leaves the battery compartment 200, the first torsion spring 32 provides elastic force, preventing the second plate 312 from switching to the second position under slight external force. In other examples, the battery body 10 or the discharge socket 20 may be provided with a structure that engages with the second plate 312, keeping the second plate 312 in the first position.
[0052] In some examples, such as Figure 3 As shown, the discharge socket 20 has a connecting ear 21 on its lower vertical side, and the connecting part 313 is rotatably connected to the connecting ear 21. With this configuration, the locking plate 31 is rotatably connected to the connecting ear 21 via its connecting part 313 and is directly rotatably mounted on the discharge socket 20. This configuration results in a simple locking device structure for the discharge socket 20, facilitating production and assembly. Of course, in other embodiments, a mounting base 33 can be fixedly mounted on the discharge socket 20, and then the locking plate 31 can be rotatably mounted on the mounting base 33.
[0053] In some examples, such as Figures 4 to 6As shown, the socket locking device 30 also includes a mounting base 33 and a flip cover 34. The mounting base 33 is fixedly installed on the discharge socket 20. The mounting base 33 is also rotatably mounted with a locking plate 31. The flip cover 34 is rotatably installed on the mounting base 33. The flip cover 34 is provided with an abutment part 3431. When the electric vehicle battery 100 is placed in the battery compartment 200 of the battery swapping cabinet 1000, the flip cover 34 abuts against the wall of the battery compartment 200, and the abutment part 3431 abuts against the locking plate 31 to restrict the rotation of the locking plate 31.
[0054] The mounting base 33 can take many different forms, for example: Figure 6 As shown, the mounting base 33 includes two sub-bases, which are respectively fixedly installed on both sides of the discharge socket 20. For example: Figure 9 As shown, the mounting base 33 includes structures such as a sub-base, a bushing, and a damping ring, and for example: Figure 12 As shown, the mounting base 33 is long and narrow, and is fixedly connected to both sides of the discharge socket 20.
[0055] In this example, the locking plate 31 can be rotatably mounted on the upper side of the mounting base 33. Specifically, the locking plate 31 is rotatably connected to the mounting base 33 above the socket 23 of the discharge socket 20. In this configuration, the locking plate 31 can cover the socket 23 using gravity. The locking plate 31 can also be rotatably mounted on the lower side of the mounting base 33. Specifically, the locking plate 31 is rotatably connected to the mounting base 33 below the socket 23 of the discharge socket 20.
[0056] With this configuration, after the electric vehicle battery 100 is placed in the battery compartment 200 of the battery swapping cabinet 1000, the abutting part 3431 of the flip cover 34 abuts against the locking plate 31, and the flip cover 34 abuts against the wall of the battery compartment 200. Thus, the flip cover 34 is restricted from rotating, and the abutting part 3431 remains in contact with the locking plate 31, which tightly blocks the insertion hole 23. After the electric vehicle battery 100 is removed from the battery compartment 200, the flip cover 34 no longer engages with the battery compartment 200, and the locking plate 31 can move under external force. This ensures that the electric vehicle battery 100 is protected by a lock while inside the battery compartment 200, improving the safety of the electric vehicle battery 100.
[0057] In some examples, such as Figure 6 As shown, the flip cover 34 includes a drive plate 341, a connecting plate 342, and an abutment plate 343. The drive plate 341 and the abutment plate 343 are arranged parallel to each other. One side of the drive plate 341 is rotatably mounted on the mounting base 33, and the other side of the drive plate 341 is connected to the connecting plate 342. The connecting plate 342 is also connected to the abutment plate 343. The abutment plate 343 is provided with an abutment part 3431.
[0058] With this configuration, a space is created between the drive plate 341 and the abutment plate 343, facilitating the abutment portion 3431 to engage with the locking plate 31. Furthermore, this structural configuration allows the flip cover 34 to be elastic, ensuring that the abutment portion 3431 of the flip cover 34 remains in contact with the locking plate 31 even when the electric vehicle battery 100 vibrates.
[0059] It should be emphasized that you should refer to the following: Figure 1 , Figure 4 , Figure 7 as well as Figure 10 The battery body 10 usually has a protruding part of the structure above the discharge socket 20.
[0060] In some examples, such as Figures 7 to 12 As shown, the discharge socket 20 has a mounting surface 22, and the mounting surface 22 is recessed with a socket 23; the socket locking device 30 also includes a mounting base 33, which is fixedly mounted on the discharge socket 20. A locking plate 31 is rotatably mounted on one side of the mounting base 33. The axis of rotation of the locking plate 31 is perpendicular to the mounting surface 22 and is located on one side of the socket 23 in the horizontal direction. When the electric vehicle battery 100 is placed in the battery compartment 200 of the battery swapping cabinet 1000, the two sides of the locking plate 31 abut against the compartment wall of the battery compartment 200 and the battery body 10 respectively to restrict the rotation of the locking plate 31.
[0061] With this configuration, after switching the locking plate 31 to the first position, the electric vehicle battery 100 is placed in the battery compartment 200. The locking plate 31 abuts against the electric vehicle body from the top vertical direction and against the compartment wall of the battery compartment 200 from the bottom vertical direction, tightly blocking the socket 23. After the electric vehicle battery 100 is removed from the battery compartment 200, the locking plate 31 no longer engages with the battery compartment 200 and can move under external force. This solution is also simpler in structure compared to other solutions mentioned above. Furthermore, a structure that engages with the locking plate 31 can be provided on the battery body 10 or the discharge socket 20 to keep the locking plate 31 in the first position.
[0062] In some examples, such as Figures 7 to 12 As shown, the locking plate 31 is further provided with a locking rod 314 extending along it; the socket locking device 30 also includes a locking member 35, which is rotatably mounted on the side of the mounting base 33 away from the locking plate 31, and the axis of rotation of the locking member 35 is parallel to the mounting plane 22. The locking member 35 is provided with a sliding part 351 and a locking part 352 respectively. When the electric vehicle battery 100 is placed in the battery compartment 200 of the battery swapping cabinet 1000, the sliding part 351 cooperates with the compartment wall of the battery compartment 200, so that the locking part 352 cooperates with the locking rod 314 to lock the locking rod 314 to the locking member 35.
[0063] With this configuration, after the electric vehicle battery 100 is placed in the battery compartment 200 of the battery swapping cabinet 1000, the sliding part 351 of the locking member 35 engages with the compartment wall of the battery compartment 200. The locking member 35 is restricted by the compartment wall of the battery compartment 200 and cannot release the engagement between the locking part 352 and the locking rod 314, thereby locking the locking rod 314 to the locking member 35. In this way, the rotation of the locking plate 31 is further restricted by the locking member 35, thereby further improving the safety performance of the electric vehicle battery 100.
[0064] The locking portion 352 on the aforementioned locking member 35 has various configuration forms. In some examples, the locking portion 352 is movable, such as... Figures 10 to 12 As shown, one end of the locking member 35 is rotatably mounted on the mounting base 33, and the other end of the locking member 35 is movably provided with a locking part 352. In some examples, such as Figures 7 to 9 As shown, the locking part 352 is fixed to the locking member 35.
[0065] In some examples, such as Figure 5 and Figure 6 As shown, a second torsion spring 36 is also provided between the locking member 35 and the mounting base 33 to elastically drive the locking member 35 to keep the locking part 352 engaged with the locking rod 314. This arrangement aims to provide elastic force through the second torsion spring 36 so that after the electric vehicle battery 100 is detached from the battery compartment 200, the locking plate 31 is not affected by gravity and can still block the socket 23. In other examples, a structure that engages with the locking plate 31 can be provided on the battery body 10 or the discharge socket 20, so that the locking plate 31 remains in the first position.
[0066] In some examples, the discharge socket 20 has a mounting surface 22 with a recessed insertion hole 23, and the locking plate 31 is slidably mounted on the mounting base 33 in a horizontal direction. In this configuration, the locking plate 31 can be locked in a first position by the aforementioned raised flip cover 34.
[0067] The above description is merely an optional embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
