Description

Technical Field

[0001] This utility model relates to the field of vehicle battery swapping technology, specifically to a battery pack locking structure for vehicles. Background Technology

[0002] Existing electric vehicle battery pack installation methods are generally divided into fixed and replaceable types. Replaceable battery packs typically use a movable installation method, allowing the battery pack to be removed and replaced with a new one at any time. The process of replacing a new battery pack involves locking and unlocking the pack.

[0003] The locking and unlocking of the battery pack relies on a battery pack locking device. Existing locking devices include an upper locking body fixed to the vehicle end and a lower locking body fixed to the battery pack end. The upper and lower locking bodies cooperate to lock and unlock via a lock cylinder assembly. To prevent sand from entering the lower locking body during vehicle operation, a seal is usually installed at the bolt output position of the lower locking body. The bolt passes through the central through hole of the seal, which is typically made of rubber.

[0004] However, during the locking and unlocking process, the rising and falling of the locking tongue can cause deformation of the seal, which in turn pulls on the central through hole, resulting in a reduction in the sealing performance of the seal. Utility Model Content

[0005] The purpose of this utility model is to provide a battery pack locking structure for vehicles, which solves the problem that in the prior art, the rising and falling of the locking tongue during the locking and unlocking process causes deformation of the sealing element, thereby pulling the central through hole and reducing the sealing performance of the sealing element.

[0006] To achieve the above objectives, this utility model provides a battery pack locking structure for vehicles, including... The first lock body is used to connect to the vehicle end; The second lock body is used to connect to the battery pack end; The lock cylinder assembly is installed in the second lock body and works with the first lock body to unlock and lock the battery pack and the vehicle. The lock cylinder assembly includes a bolt that passes through the top of the second lock body and engages with the first lock body; a sealing sleeve is provided at the top of the second lock body, the sealing sleeve has a central through hole, the bolt passes through the central through hole, and the central through hole is in close contact with the bolt; the top surface of the sealing sleeve has an annular protrusion corresponding to the edge of the central through hole.

[0007] Furthermore, the diameter of the central through hole is the same as the outer diameter of the latch, and the height of the annular protrusion is 0.3mm~0.5mm.

[0008] Furthermore, the top of the second lock body is provided with a check ring cover, the check ring cover includes a cover seat and a cover boss provided on the top surface of the cover seat, the central hole is provided through the cover seat and the cover boss; the sealing sleeve covers the cover boss.

[0009] Furthermore, the outer periphery of the ring cover boss is provided with a groove that tapers inward toward the central hole, and the sealing sleeve is provided with a edging portion corresponding to the groove, the edging portion extending toward the groove.

[0010] Furthermore, the top surface of the ring cover boss is provided with multiple protrusions, and the sealing sleeve is provided with assembly holes corresponding to the protrusions.

[0011] Furthermore, the height of the protrusion is 1.3mm to 1.7mm.

[0012] Furthermore, the ring cover seat has multiple threaded holes, and the check ring cover is fixed to the top of the second lock body by bolts engaging with the threaded holes.

[0013] Furthermore, the latch is provided with a baffle surrounding its outer circumference, and the baffle is provided with a limiting block protruding from its outer side; the central hole has the same shape as the baffle, and the ring cover boss is provided with a through groove at the edge of the central hole for the limiting block to pass through.

[0014] Furthermore, a pressure block is fixedly provided at the top of the latch, and an unlocking nut is movably provided at the bottom; the unlocking nut rotates around the axial direction of the latch under the drive of an external drive component, causing the latch to rotate and move simultaneously along the Z direction, thereby causing the pressure block to switch between the unlocked position and the locked position on the first lock body.

[0015] Furthermore, the bottom end of the second lock body is provided with an unlocking port, and a second anti-return element is provided on the inner wall of the second lock body near the unlocking port; a first anti-return element is slidably connected to the outer side of the unlocking nut, and the unlocking nut is prevented from rotating when the first anti-return element and the second anti-return element are engaged, and the unlocking nut can rotate when they are separated.

[0016] Compared with existing known technologies, the technical solution provided by this utility model has the following beneficial effects: This utility model discloses a battery pack locking structure for vehicles. A sealing sleeve is positioned at the top of the second lock body. The central through-hole of the sealing sleeve is tightly fitted with the lock tongue, achieving a zero-contact seal between the sealing sleeve and the lock tongue. This significantly improves the sealing performance of the second lock body and prevents sand from entering the lock body during vehicle operation. Furthermore, an annular protrusion is provided at the edge of the central through-hole, increasing the structural strength of the sealing sleeve at that location and enhancing its resistance to deformation. This prevents the central through-hole of the sealing sleeve from being deformed by the lock tongue pulling it up and down.

Detailed Implementation

[0021] The present invention will now be described in detail with reference to the accompanying drawings. The embodiments described herein are merely preferred embodiments of the present invention. Those skilled in the art can conceive of other ways to implement the present invention based on the preferred embodiments, and such other ways also fall within the scope of the present invention.

[0022] Reference Figures 1-15 This embodiment provides a battery pack locking structure for vehicles, including a first lock body 100 for connecting to the vehicle end; a second lock body 200 for connecting to the battery pack end; and a lock cylinder assembly 300, installed in the second lock body 200 and cooperating with the first lock body 100 to achieve locking and unlocking between the battery pack end and the vehicle end. During the locking or unlocking process of the lock cylinder assembly 300, generally, the first lock body 100 is located above, and the second lock body 200 is located below.

[0023] Among them, such as Figure 1 and Figure 2 As shown, a first lock hole 110 is provided in the middle of the first lock body 100. The first lock hole 110 is elongated. Two limiting protrusions 120 are symmetrically provided on the top surface of the first lock body 100 about the center of the first lock hole 110. The limiting protrusions 120 limit the rotation position of the lock cylinder assembly 300 when the lock cylinder assembly 300 is locked.

[0024] The lock cylinder assembly 300 includes a bolt 310, which is cylindrical in shape. A pressure block 320, also elongated in shape, is fixedly connected to the top of the bolt 310. When the pressure block 320 rotates with the bolt 310 to be parallel to the first lock hole 110, it can pass through the first lock hole 110 to unlock; at this time, the pressure block 320 is in the unlocked position. When the pressure block 320 passes through the first lock hole 110 and is above it, and then rotates to a direction perpendicular to the first lock hole 110, the pressure block 320 presses against the first lock hole 110 and is limited by the limiting protrusion 120; at this time, it is in the locked position.

[0025] The latch 310 is provided with a limiting structure to restrict the rotation angle of the latch 310 around its axial direction. In this embodiment, the restricted rotation angle is 90°. A check ring cover 210 is provided at the top of the second lock body 200, which is used to restrict the Z-axis movement of the latch 310. The latch 310 extends into the second lock body 200 through the central hole 211 of the check ring cover 210. In actual manufacturing and testing, the thickness of the limiting structure of the latch 310 and the thickness of the check ring cover 210 are increased to improve the structural strength of the lock body. To avoid assembly difficulties, the check ring cover 210 is provided with a through groove 212 at the edge of the central hole 211 for the limiting structure to pass through. During assembly, the latch 310 passes through the central hole 211 and the limiting structure passes through the through groove 212, which has good passage and reduces assembly difficulty. The limiting structure and the through slot 212 are staggered when the battery pack is unlocked and locked, ensuring that the locking tongue 310 will not accidentally disengage during the locking and unlocking process, thus improving the safety of the battery pack during the battery swapping process.

[0026] To improve the assembly efficiency of the locking structure during the manufacturing process and to prevent the revolute cover 210 from being installed backwards by production personnel, in some embodiments, such as Figures 5-9 As shown, at least two through slots 212 are provided, and their shapes are the same as those of the limiting structure. The through slots 212 are symmetrical about the central hole 211. The two symmetrical through slots 212 allow production personnel to assemble the device from any direction, whether left or right, thus serving as a foolproof design and improving assembly efficiency.

[0027] As one embodiment of the check ring cover 210 structure, such as Figures 7-9 As shown, the check ring cover 210 includes a cover base 213 and a cover boss 214 disposed on the top surface of the cover base 213. A central hole 211 is provided through the cover base 213 and the cover boss 214. The cover base 213 serves as the foundation for the check ring cover 210 to be mounted on the second lock body 200. The cover base 213 has multiple threaded holes 216, and the check ring cover 210 is fixed to the top of the second lock body 200 by bolts engaging with the threaded holes 216. The cover boss 214 primarily serves to limit the axial movement of the latch 310.

[0028] Furthermore, in some embodiments, the outer periphery of the ring cover boss 214 is provided with a groove 215 that tapers inward toward the central hole 211, thereby giving the top periphery of the ring cover boss 214 an outward convex structure. The sealing sleeve 240 is provided with an edge portion 243 corresponding to the groove 215, extending toward the groove 215. The edge portion 243 cooperates with the groove 215 to securely fit the sealing sleeve 240 onto the ring cover boss 214, preventing the sealing sleeve 240 from falling off during vehicle operation.

[0029] To ensure the sealing of the second lock body 200, such as Figure 3 and Figure 4 As shown, a sealing sleeve 240 is provided covering the ring cover boss 214. The sealing sleeve 240 has a central through hole 241, the diameter of which is the same as the outer diameter of the latch 310. The sealing sleeve 240 is mainly made of rubber. The central through hole 241 is in close contact with the latch 310, achieving a zero-contact seal between the sealing sleeve 240 and the latch 310. This greatly improves the sealing performance of the second lock body 200 and prevents sand from entering the lock body during vehicle operation.

[0030] It is understandable that the sealing sleeve 240 is made of rubber, and when the locking tongue 310 moves up and down, the central through hole 241 may deform, thereby affecting the sealing effect of the sealing sleeve 240. To reduce the risk of reduced sealing performance due to deformation, in some embodiments, such as... Figures 10-11 As shown, an annular protrusion 242 is provided on the top surface of the sealing sleeve 240 around the edge of the central through hole 241. The annular protrusion 242 can increase the structural strength at the position of the central through hole 241 and improve the resistance to deformation. When the locking tongue 310 moves up and down, the annular protrusion 242 can prevent the position of the central through hole 241 of the sealing sleeve 240 from being pulled up and down by the locking tongue 310 and deformed.

[0031] Furthermore, during the testing of this device, it was found that the annular protrusion 242 facilitates the injection of oil into the second lock body 200, enabling maintenance and lubrication of the second lock body 200 and improving the service life of the device. Specifically, the height of the annular protrusion 242 is 0.3mm to 0.5mm, with possible values ​​including 0.3mm, 0.35mm, 0.4mm, 0.45mm, and 0.5mm, of which 0.5mm is the most preferred value.

[0032] It should be noted that in some embodiments, such as Figure 8As shown, the top surface of the ring cover boss 214 is provided with multiple protrusions 217, and the sealing sleeve 240 has mounting holes 244 corresponding to the protrusions 217. There are four protrusions 217, located near the four corners of the ring cover boss 214. The height of the protrusions 217 is 1.3mm to 1.7mm, and can be 1.3mm, 1.4mm, 1.5mm, 1.6mm, and 1.7mm, with 1.5mm being the most preferred. Since the sealing sleeve 240 is made of rubber, it will be compressed during the locking process. The protrusions 217 can limit the amount of compression of the rubber sealing sleeve 240, thereby improving its service life.

[0033] As one embodiment of the lock cylinder assembly 300, such as Figure 13 As shown, the latch 310 is provided with a baffle 311 surrounding its outer circumference, and a limiting structure is a limiting block 312, which protrudes from the outer side of the baffle 311. A pressure block 320 is fixedly provided at the top of the latch 310, and an unlocking nut 330 is movably provided at the bottom. The unlocking nut 330 rotates around the axial direction of the latch 310 under the drive of an external driving component, causing the latch 310 to rotate and move simultaneously along the Z direction, thereby causing the pressure block 320 to switch between the unlocked position and the locked position on the first lock body 100.

[0034] Specifically, the unlocking nut 330 is threadedly connected to the bottom end of the locking tongue 310. The unlocking nut 330 is restricted from Z-axis movement by the second lock body 200 but can rotate freely around the axial direction. The second lock body 200 is a split structure, including a second upper lock body 220 and a second lower lock body 230. The second upper lock body 220 is threadedly connected inside the second lower lock body 230. The end wall of the second upper lock body 220 blocks the unlocking nut 330, restricting its Z-axis movement. Multiple recesses 231 are provided on the outer surface of the second lower lock body 230 near its lower end, surrounding the second lower lock body 230. The recesses 231 can be used with external wrenches or other components to tighten or loosen the second lower lock body 230 and the second upper lock body 220, improving assembly efficiency.

[0035] The top of the unlocking nut 330 has an extension 331, which is a relatively flat cylindrical shape, and its outer contour extends beyond the outer contour of the unlocking nut 330. A first friction plate 350 and a second friction plate 360 ​​are disposed between the baffle 311 and the extension 331, both of which are fitted onto the outer side of the latch 310. A compression spring 370 connects the first friction plate 350 and the second friction plate 360, which presses the first friction plate 350 tightly against the top surface of the baffle 311 and the second friction plate 360 ​​tightly against the bottom surface of the baffle 311. This increases the friction between the latch 310 and the unlocking nut 330, causing the unlocking nut 330 to drive the latch 310 to rotate synchronously.

[0036] It should be noted that the shape of the central hole 211 of the check ring cover 210 is consistent with the shape of the baffle 311, and the central hole 211 can be circular or non-circular. When the baffle 311 is non-circular, the central hole 211 is a non-circular shape that matches the baffle 311. During unlocking, the bolt 310 rises along the Z direction, increasing the contact area between the bolt 310 and the central hole 211, which can improve the stability of the unlocking process.

[0037] It is understandable that after locking, the unlocking nut 330 needs to be prevented from rotating to prevent disengagement. As one implementation of the second lock body 200, such as... Figure 14 As shown, the bottom end of the second lock body 200 is provided with an unlocking port 232, and a second check piece 233 is provided on the inner wall of the second lock body 200 near the unlocking port 232; a first check piece 340 is slidably connected to the outer side of the unlocking nut 330. When the first check piece 340 and the second check piece 233 are engaged, the unlocking nut 330 is prevented from rotating, and when they are separated, the unlocking nut 330 can rotate.

[0038] Preferably, the first check ring 340 is a first gear ring with an inner hole that matches the outer contour of the unlocking nut 330. The first gear ring has downward-facing meshing teeth. A return spring 380 is connected between the first gear ring and the outer extension 331. Pushing the first gear ring compresses the return spring 380. The return spring 380 can push the first gear ring to its reset position without external force. The second check ring 233 is a second gear ring fixed to the inner wall of the second lock body 200. The second gear ring has meshing teeth corresponding to those of the first gear ring. Under the action of the return spring 380, the first gear ring and the second gear ring are tightly engaged, preventing the unlocking nut 330 from rotating.

[0039] When locking, the unlocking nut 330 is driven to rotate clockwise. At this time, due to the elastic force of the compression spring 370, the first friction plate 350 is in close contact with the baffle 311 on the latch 310, and the second friction plate 360 ​​is in close contact with the unlocking nut 330, thereby increasing the friction between the latch 310 and the unlocking nut 330. The unlocking nut 330 drives the latch 310 to rotate synchronously. When the latch 310 rotates from the first angle to the second angle, the pressure block 320 passing through the first lock hole 110 abuts against the limiting protrusion 120 at both ends and remains perpendicular to the first lock hole 110, making it impossible to pass through the first lock hole 110. At this time, the latch 310 cannot continue to rotate. Continue to drive the unlocking nut 330 to rotate clockwise. Under the action of the thread, the unlocking nut 330 will drive the second lock body 200 to move axially along the lock tongue 310 towards the first lock body 100, so that the pressure block 320 is perpendicularly pressed against the surface of the first lock body 100 on both sides of the first lock hole 110, forming a mechanical interlock, thereby installing the battery on the second lock body 200 onto the electric vehicle. After tightening the unlocking nut 330, remove the unlocking tool. Under the action of the return spring 380, the meshing teeth of the first gear ring and the meshing teeth of the second gear ring will resume meshing, and the unlocking nut 330 and the second lock body 200 will be locked at an angle and cannot be rotated.

[0040] During unlocking, the first gear ring is lifted, compressing the return spring 380, causing the first gear ring to disengage from the second gear ring and releasing the anti-reverse lock. At this time, the unlocking nut 330 can rotate freely within the second lock body 200; then, a tool is used to drive the unlocking nut 330 to rotate counterclockwise. At this time, because the pressure block 320 at the end of the latch 310 is perpendicularly pressed against the surface of the first lock body 100 on both sides of the first lock hole 110, the static friction generated is much greater than the friction between the latch 310 and the unlocking nut 330. The latch 310 still cannot rotate with the unlocking nut 330. Under the action of the thread, the unlocking nut 330 will drive the second lock body 200 to move in the opposite direction along the axial direction of the latch 310. As the pressure of the pressure block 320 pressing against the surface of the first lock body 100 on both sides of the first lock hole 110 gradually decreases, the static friction generated also gradually decreases. The unlocking nut 330 will drive the lock tongue 310 to rotate counterclockwise from the second angle to the first angle. The pressure block 320 is parallel to the first lock hole 110 of the first lock body 100. At this time, the pressure block 320 can be pulled out from the first lock hole 110 of the first lock body 100, and the battery on the second lock body 200 can be removed from the electric vehicle.
