Description

Technical Field

[0001] This invention relates to the field of vehicle battery fixing technology, and more specifically, to a floating lock and battery swapping system. Background Technology

[0002] Removable batteries for battery swapping are a common and effective way to quickly recharge electric vehicles and ensure continuous operation. However, compared to battery packs fixed to the vehicle, replaceable battery packs present the challenge of securing them to the vehicle frame.

[0003] Due to the use of a quick-detachable connection structure, the existing battery pack locking mechanism has relatively low locking strength with the battery pack, making the battery pack prone to shaking and resulting in unstable locking. Furthermore, during vehicle operation, the battery pack is also subjected to lateral forces during cornering and other maneuvers, causing it to deflect laterally relative to the vehicle frame, a problem that conventional existing locking structures struggle to address. Summary of the Invention

[0004] To address the problem of insufficient stability and easy shaking of the locked component when locked by the locking body, this invention provides a floating lock and a battery swapping system.

[0005] The first aspect of the present invention provides a floating lock, comprising: a lock body, the lock body including a housing, a latch member, a locking member, and an actuator assembly; the housing having a receiving space for accommodating the latch member, the locking member, and the actuator assembly, and an upwardly extending notch on the lower side of the housing; the latch member being C-shaped, including a latch portion and a locking portion, the latch portion being disposed below the locking portion; the locking member being V-shaped, including a driving portion and a wedge-shaped portion, the wedge-shaped portion including a locking surface facing downward, the wedge-shaped portion abutting against the locking surface from the lower side; the latch member and the locking member being respectively hinged to both sides of the notch and capable of rotating in opposite directions; the lock body includes a lock... The lock body has a locked state and an unlocked state. In the unlocked state, the bolt member is located within the receiving space. In the locked state, the bolt member can extend into the notch from one side and extend to the other side of the notch. A gap area is provided between the upper side of the bolt member and the lower side of the notch. The gap area can accommodate the locking rod, and the locking rod can be fixed between the notch and the bolt member. The drive assembly includes a first drive and a second drive. The first drive is connected to the drive unit, and the second drive is connected to the bolt member and can drive the bolt member to move towards the locked state. The first drive can drive the locking member to rotate so that the lock body can switch between the locked state and the unlocked state.

[0006] In some embodiments, the floating lock further includes a connector for connecting to the vehicle body and a first floating assembly. The lock body is connected to the connector via the first floating assembly. The first floating assembly includes an inner core, a first flexible member, and a connecting cylinder. The lock body is connected to the connecting cylinder. The first flexible member is made of a flexible material and is configured as a cylindrical structure along the extension direction of the vehicle body. The inner core is disposed on the inner side of the first flexible member and is fixedly connected to the connector.

[0007] In some embodiments, the floating lock further includes a second floating assembly, which includes an outer sleeve extending in a vertical direction and a second flexible member. The second flexible member is made of a flexible material, and the inner circumferential surface of the outer sleeve has a circular cross-section. The second flexible member is fitted to the inner circumferential surface of the outer sleeve. The locked member also includes a guide member that is spaced apart from the locking rod. The guide member is configured to extend in a vertical direction and match the inner surface of the second flexible member. The top end of the guide member is configured to be tapered.

[0008] In some embodiments, the floating lock further includes a third floating component disposed between the first floating component and the lock body. The third floating component includes a third flexible member extending along the width direction of the vehicle. Two third flexible members are provided, and the two third flexible members are respectively disposed on both sides of the lock body.

[0009] In some embodiments, the first flexible member includes a plurality of sub-flexible members, which are spaced apart along the axial direction; connecting ribs are provided between the plurality of sub-flexible members.

[0010] In some embodiments, in the locked state, the locking surface is configured to gradually extend downward in a direction away from the locking member, and the top surface of the wedge portion is provided with a wedge-shaped surface, the extension direction of which matches the locking surface.

[0011] In some embodiments, the drive assembly further includes a third drive connected to the locking member, the third drive being used to drive the wedge portion to rotate toward the locking tongue member.

[0012] In some embodiments, a limiting structure fixedly connected to the outer shell is also provided in the accommodating space. In the locked state, the limiting structure abuts against the upper side of the locking part; the locking part is provided with a groove that matches the shape of the limiting structure.

[0013] In some embodiments, in the locked state, the distance between the upper side of the latch and the upper side of the notch is less than the diameter of the locking lever.

[0014] In some embodiments, the width of the notch is set to gradually decrease from bottom to top; the first actuator is a drive cylinder, and the moving end of the drive cylinder can move in the vertical direction.

[0015] The second aspect of this application also provides a battery swapping system, including the floating lock in the above technical solution and a battery replacement device. The battery installation device is used to remove or install the battery pack from the floating lock. The battery replacement device includes a battery support mechanism, a control component, and a power source. The battery support mechanism is used to support the battery pack and drive the battery pack to move. The control component and the power source are both mounted on the battery support mechanism. The power source can provide driving power to the drive assembly. The control component is used to control the power output of the power source. The battery support mechanism is used to drive the power source to connect with the drive assembly.

[0016] To address the problem of insufficient stability and easy shaking of the locked component when locked by the locking body, the present invention has the following advantages:

[0017] In the above technical solution, the locking tongue component and the notch on the outer shell form a structure that can accommodate and hold the locking rod. In actual use, the locking rod is part of the locked component. When it is installed in the floating lock, that is, during the process of the lock body changing from the unlocked state to the locked state, the locking rod moves upward under the drive of the relevant equipment. After entering the notch, it contacts the locking part and continues to push against the locking part, causing the locking tongue to rotate, so that the locking tongue turns to the lower side of the locking rod. At the same time, due to the rotation of the locking part, the locking component, which could originally abut against the side of the locking part, rotates towards the locking tongue component and abuts against the lower side of the locking part, thereby preventing the locking part from rotating downward in the opposite direction. When the locking rod moves to the uppermost end of the notch, the locking rod will be locked between the notch and the locking tongue. If the drive assembly can drive the locking component to maintain the locked state, and when unlocking is required, the drive assembly can drive the locking component to rotate in the opposite direction, thereby moving it out from the lower side of the locking part. At this time, the locking tongue is no longer limited. Therefore, the locking rod can drive the locking tongue component to rotate under the action of gravity and finally disengage from the notch, thus completing the unlocking process. During the above process, especially during the locking process, the locking component always maintains a rotational tendency toward the latch. Therefore, when the latch rotates clockwise, the locking component can gradually penetrate into the latch and maintain a contact state. When the locking lever moves to its highest position, it will be directly fixed. In situations such as vehicle operation, even if the locked part vibrates vertically, the locking lever is completely fixed, which can effectively prevent the locking lever from moving relative to the lock body and causing impact.

[0027] This embodiment discloses a floating lock, such as Figure 1-6As shown, the lock body 10 may include: a housing 11, a latch member 12, a locking member 13, and an actuator assembly; the housing 11 has a receiving space 111 for accommodating the latch member 12, the locking member 13, and the actuator assembly; the housing 11 has an upwardly extending notch 112 on its lower side; the latch member 12 is C-shaped and includes a latch portion 121 and a locking portion 122, with the latch portion 121 located below the locking portion 122; the locking member 13 is V-shaped and includes a driving portion 131 and a wedge-shaped portion 132, with the wedge-shaped portion 132 including a locking surface facing downwards, and the wedge-shaped portion 132 abutting against the locking surface from below; the latch member 12 and the locking member 13 are respectively hinged to both sides of the notch 112 and can rotate in opposite directions; the lock body 10 is in a locked state. In the unlocked state, the latch member 12 is located within the receiving space 111. In the locked state, the latch 121 can extend into the notch 112 from one side and extend to the other side of the notch 112. A gap area is provided between the upper side of the latch 121 and the lower side of the notch 112. The gap area can accommodate the locking rod 21, and the locking rod 21 can be fixed between the notch 112 and the latch 121. The drive assembly includes a first drive 141 and a second drive 142. The first drive 141 is connected to the drive unit 131, and the second drive 142 is connected to the latch member 12 and can drive the latch member 12 to move towards the locked state. The first drive 141 can drive the locking member 13 to rotate so that the lock body 10 can switch between the locked state and the unlocked state.

[0028] In the above technical solution, the locking tongue member 12 and the notch 112 on the outer shell 11 form a structure that can accommodate and clamp the locking rod 21. In actual use, the locking rod 21 is part of the locked component. When it is installed in the floating lock, that is, during the process of the lock body 10 changing from the unlocked state to the locked state, the locking rod 21 moves upward under the drive of the relevant equipment. After entering the notch 112, it contacts the locking part 122 and continues to push against the locking part 122, causing the locking tongue part 121 to rotate, so that the locking tongue part 121 turns to the lower side of the locking rod 21. At the same time, due to the rotation of the locking part 122, the locking member 13, which could originally abut against the side of the locking part 122, is also affected. The locking lever 21 rotates towards the latch member 12 and abuts against the lower side of the locking part 122, thereby preventing the locking part 122 from rotating downwards in the opposite direction. When the locking lever 21 moves to the uppermost end of the notch 112, the locking lever 21 will be locked between the notch 112 and the latch member 121. If the actuator assembly can drive the locking member 13 to maintain the locked state, and when unlocking is required, the actuator assembly can drive the locking member 13 to rotate in the opposite direction, thereby moving it out from the lower side of the locking part 122. At this time, the latch member 121 is no longer limited. Therefore, the locking lever 21 can drive the latch member 12 to rotate under the action of gravity and finally disengage from the notch 112, thereby completing the unlocking process. During the above process, especially during the locking process, the locking member 13 always maintains a rotational tendency toward the latch 121. Therefore, when the latch 121 rotates clockwise, the locking member 13 can gradually penetrate into the latch 121 and maintain a contact state. When the locking rod 21 moves to the highest position, it will be directly fixed. In situations such as vehicle operation, even if the locked part vibrates vertically, since the locking rod 21 has been completely fixed, it can effectively prevent the locking rod 21 from moving relative to the lock body 10 and causing impact.

[0029] It should be noted that the first driver 141 and the second driver 142 may have the same or different structures. They may be controllable drive cylinders, hydraulic cylinders, or torsion springs or other elastic elements with a preset torque direction.

[0030] Although the battery pack is locked to the lock body 10, it still experiences vertical vibrations during actual driving. When turning, it also experiences lateral forces that cause it to deflect laterally. If a rigid structure is used to connect the battery pack to the vehicle frame with high strength, long-term use will inevitably lead to swaying of the battery pack relative to the vehicle body due to structural aging. Therefore, while ensuring the lock body 10 remains locked, the battery pack can be allowed to adapt to the acceleration and forces it experiences, allowing both the lock body 10 and the battery pack to move simultaneously relative to the vehicle body within a certain range. This can extend the fixing effect of the device and ensure connection stability. For example... Figure 4-5As shown, the floating lock also includes a connector 30 for connecting to the vehicle body and a first floating assembly 40. The lock body 10 is connected to the connector 30 through the first floating assembly 40. The first floating assembly 40 includes an inner core 41, a first flexible member 42, and a connecting cylinder 43. The lock body 10 is connected to the connecting cylinder 43. The first flexible member 42 is made of flexible material and is configured as a cylindrical structure along the extension direction of the vehicle body. The inner core 41 is disposed on the inner side of the first flexible member 42 and is fixedly connected to the connector 30.

[0031] Using the first floating component 40, when the vehicle is subjected to a force in the vertical or horizontal direction, the connecting cylinder 43 can undergo radial displacement relative to the inner core 41. At this time, the first flexible member 42 can be squeezed in the radial direction, thereby achieving a buffering effect. When the vehicle is subjected to a force along the length of the vehicle, the first floating component 40 can be squeezed in the axial direction. Since the first flexible member 42 is made of a flexible material, such as rubber, it can undergo elastic deformation to reduce the transmission of vibration. At the same time, since the first floating component 40 is composed of multiple cylindrical structures nested together, the lock body 10 can also rotate relative to the connecting member 30. When the vehicle sways laterally, the battery pack can adapt to the swaying of the vehicle within a certain range with the help of the first floating component 40, thereby reducing the force of the battery on the vehicle itself, and the locking of the lock body 10 is not affected.

[0032] Furthermore, to further ensure the stability of the battery pack, such as Figure 1 , Figure 4 As shown, the floating lock also includes a second floating component 50, which includes an outer sleeve 51 extending in a vertical direction and a second flexible member 52. The second flexible member 52 is made of a flexible material. The inner circumferential surface of the outer sleeve 51 has a circular cross-section. The second flexible member 52 is attached to the inner circumferential surface of the outer sleeve 51. The locked component also includes a guide member 22 that is spaced apart from the locking rod 21. The guide member 22 is configured to extend in a vertical direction and match the inner side surface of the second flexible member 52. The top end of the guide member 22 is set to be conical.

[0033] In practical use, a guide 22 can be provided to guide the installation of the battery pack. The guide 22 is inserted into the vertically set sleeve to play a guiding role. In the above solution of this application, a second flexible member 52 is added. When the vehicle is subjected to horizontal force, the guide 22 can squeeze the second flexible member 52 around it to achieve the purpose of shock absorption. When subjected to force in the length direction of the vehicle, it can cooperate with the first flexible member 42 to provide shock absorption at the same time. When lateral sway occurs, the first floating component 40 can rotate, and at this time, the guide 22 can also squeeze the second flexible member 52.

[0034] Furthermore, to prevent the floating lock or battery pack from colliding with the frame or body during lateral swaying, such as Figure 6 As shown, the floating lock also includes a third floating component, which is disposed between the first floating component 40 and the lock body 10. The third floating component includes a third flexible member 61 extending along the width direction of the vehicle. There are two third flexible members 61, which are respectively disposed on both sides of the lock body 10.

[0035] When the vehicle sways laterally, although the first floating component 40 can rotate, when the lock body 10 gets too close to the frame, the third flexible component 61 can be wider than the width of the lock body 10, so that the third flexible component 61 makes contact first, thereby achieving the effect of buffering and limiting the excessive swaying of the lock body 10.

[0036] As a further embodiment, in order to make the compression amount of the first flexible member 42 in the axial direction match the compression amount of the second flexible member 52, the first flexible member 42 includes a plurality of sub-flexible members, which are spaced apart in the axial direction; and connecting ribs are provided between the plurality of sub-flexible members.

[0037] The axial deformation of the first flexible member 42 is increased by utilizing the space between the multiple flexible sub-components. Furthermore, to prevent the spacing between the flexible sub-components from decreasing over time, multiple connecting ribs can be provided, that is, multiple hollow structures can be provided in the middle of the originally cylindrical first flexible member 42.

[0038] To ensure locking stability while in the locked state, such as Figure 2 As shown, in the locked state, the locking surface is configured to gradually extend downwards in a direction away from the locking member 13, and the top surface of the wedge-shaped portion 132 is provided with a wedge-shaped surface, the extension direction of which matches the locking surface. By forming the wedge-shaped portion 132 to gradually extend into the lower side of the locking surface, the wedge-shaped portion 132 can gradually move with the movement of the locking member 13, ensuring the locking effect.

[0039] As one implementation method, such as Figure 2 As shown, the actuator assembly also includes a third actuator 143, which is connected to the locking member 13. The third actuator 143 is used to drive the wedge portion 132 to rotate toward the latch member 12. The third actuator 143 can be a structure such as a drive cylinder or a torsion spring, and a torsion spring is preferred because it can respond more quickly to the rotation of the latch member 12 so as to rotate with the latch member 12.

[0040] To prevent the locking tongue component 12 from moving too upward, such as Figure 2As shown, a limiting structure 113 fixedly connected to the outer shell 11 is also provided in the accommodating space 111. In the locked state, the limiting structure 113 abuts against the upper side of the locking part 122; the locking part 122 is provided with a groove 1221 that matches the shape of the limiting structure 113.

[0041] To ensure sufficient force during locking and prevent the locking lever 21 from wobbling, in the locked state, the distance between the upper side of the latch and the upper side of the notch 112 is less than the diameter of the locking lever 21. In the locked state, the locking lever 21 can be squeezed to cause slight deformation, thereby achieving a stable lock through friction.

[0042] To guide the movement of the locking lever 21, especially during the installation of the battery pack, such as Figure 1-2 As shown, the width of the notch 112 is set to gradually decrease from bottom to top; the first actuator 141 is a driving cylinder, and the moving end of the driving cylinder can move in the vertical direction. During the unlocking process, the driving force of the first actuator 141 can be used to achieve the unlocking purpose.

[0043] The second aspect of this application also provides a battery swapping system, including the floating lock in the above technical solution and a battery replacement device. The battery installation device is used to remove or install the battery pack from the floating lock. The battery replacement device includes a battery support mechanism, a control component, and a power source. The battery support mechanism is used to support the battery pack and drive the battery pack to move. The control component and the power source are both mounted on the battery support mechanism. The power source can provide driving power to the drive assembly. The control component is used to control the power output of the power source. The battery support mechanism is used to drive the power source to connect with the drive assembly.

[0044] The load-bearing mechanism can be a forklift or other transport machinery. To prevent the floating lock from unlocking itself due to unexpected situations during vehicle operation, the power source of the floating lock is separated from the vehicle. Since the removal of the battery pack must be done with the help of the battery replacement device, the floating lock is only required to unlock or lock at this time. By setting the power source on the battery replacement device, the floating lock can be effectively prevented from unlocking unexpectedly in other situations. At the same time, since the power source is located outside the vehicle, the number of parts on the vehicle can be reduced, and the weight of the vehicle can be reduced.

[0045] Those skilled in the art will understand that the above embodiments are specific examples of implementing this disclosure, and in practical applications, various changes can be made in form and detail without departing from the scope of this disclosure.
