Description

Technical Field

[0001] This utility model relates to the field of locks, and in particular to a drive structure for a safety lock on an external storage box of a long-distance transport vehicle. Background Technology

[0002] The safety locks on external storage compartments of long-haul trucks are crucial for ensuring cargo security. With the advancement of electronic and intelligent lock technology, electronic control units can easily manage the opening and closing of locks. However, electronic locks are more expensive, and they also need to retain essential mechanical functions to allow for opening and locking even in the event of a power outage.

[0003] Traditional external storage compartments in long-haul trucks typically use key-operated locks, with a lock cylinder on the lid and a latch on the compartment body. For example, some protective and secure storage lockers use lock cylinders containing a lock cylinder, drive plate, latch, and return spring. The lock is opened and closed by turning the key, which drives the drive plate to extend and retract the latch. Existing external storage compartment safety lock drive structures for long-haul trucks are technologically mature, widely used, relatively simple in structure, and low in cost. However, during vehicle operation, vibrations and impacts occur, and the external locks are exposed to wind, sun, and rain. Existing mechanical locks are susceptible to damage from vibration and impacts, making their opening and closing unstable.

[0004] Therefore, it is necessary to provide a more stable and reliable safety lock drive structure for the external storage box of long-distance transport vehicles. Utility Model Content

[0005] The purpose of this utility model is to provide a more stable and reliable safety lock drive structure for the external storage box of a long-distance transport vehicle.

[0006] To achieve the above objectives, this utility model provides a safety lock drive structure for an external storage box in a long-distance transport vehicle, comprising: The housing has an inner surface and an outer surface that are disposed opposite to each other. A mounting post is provided protrudingly on the inner surface, and a limit post is also provided protrudingly. The handle is movably mounted on the outer surface; A limiting component is mounted on the inner surface and connected to one end of the handle; An operating component is mounted on the inner surface and connected to the other end of the handle; The drive assembly is mounted on the mounting post. One end of the drive assembly is close to the limiting assembly and abuts against the limiting post, and the other end of the drive assembly is close to the operating assembly. The drive assembly has a drive post protruding from it. The release assembly has a drive groove through the middle, the drive groove is sleeved on the drive column, and the two ends of the release assembly are rotatably connected to the housing. The limiting component rotates to abut against the driving component and limits the driving component from both sides with the limiting post. Pulling the handle drives the operating component to push the driving component. The driving component slides between the limiting component and the limiting post and drives the release component to rotate and release the lock.

[0007] Compared with existing technologies, the safety lock drive structure for the external storage compartment of a long-distance transport vehicle of this utility model is compact, reasonable, and easy to operate. The safety lock drive structure for the external storage compartment of a long-distance transport vehicle includes a housing, a handle, a limiting component, an operating component, a drive component, and a release component. The housing has an inner surface and an outer surface that are oppositely arranged. A mounting post protrudes from the inner surface, and a limiting post protrudes from the inner surface. The handle is movably mounted on the outer surface, and its two ends are respectively connected to the limiting component and the operating component mounted on the inner surface. The drive component is mounted on the mounting post of the housing and is located between the limiting component and the operating component. One end of the drive component is close to the limiting component and abuts against the limiting post. A drive post protrudes from the drive component, and a drive groove is formed through the middle of the release component. The drive groove is fitted onto the drive post, and both ends of the release component are rotatably connected to the housing. Specifically, when the limiting component rotates to abut against the driving component and is limited by the limiting post from both sides, pulling the handle drives the operating component to push the driving component. The driving component slides between the limiting component and the limiting post, causing the release component to rotate and release the lock. This utility model's external storage box safety lock drive structure for long-distance transport vehicles is more stable and requires a key to rotate the limiting component to a certain position before the handle can be pulled to release the lock, making it safer and more reliable.

[0008] Preferably, the housing has a first through groove, and a drive rod is provided protruding from one end of the handle. The drive rod passes through the first through groove and is connected to the operating component. The drive rod has a receiving groove. The operating component includes an operating member and a first elastic member. The driving end of the operating member passes through the receiving groove and is located in the receiving groove. The first elastic member is used to make the driving end constantly abut against the receiving groove.

[0009] The housing is provided with a mounting assembly for mounting the operating component. The end of the operating component away from the drive end is a rotating end, which is rotatably mounted in the mounting assembly. The first elastic element is mounted on the rotating end.

[0010] Preferably, a push block is provided protrudingly on the rotating end, and pulling the handle causes the drive rod to pry the drive end, so that the push block pushes the drive assembly.

[0011] Preferably, a fixing block is also provided on the rotating end, and the first elastic element is sleeved on the rotating end with one end fixed to the mounting component and the other end fixed to the fixing block.

[0012] Preferably, a second through slot is provided on the housing, and a connecting component is connected to one end of the handle. The connecting component passes through the second through slot and is connected to the limiting component, driving the handle to rotate the limiting component via the connecting component.

[0013] Preferably, the limiting component includes a first limiting block and a second limiting block, the first limiting block being connected to the second limiting block, and the driving component includes a protruding positioning post. There is an accommodating space between the first limiting block and the second limiting block for accommodating the positioning post. Rotating the limiting component causes the positioning post to be positioned at different positions in the accommodating space and abut against the first limiting block or against the second limiting block. When the positioning post abuts against the first limiting block, the first limiting block and the positioning post limit the positioning post from both sides. Pulling the handle causes the driving component to slide linearly along the first limiting block within the accommodating space.

[0014] Preferably, the first limiting block is provided with a second elastic element, which keeps the first limiting block against the positioning post.

[0015] Preferably, the housing is provided with a first mounting part and a second mounting part, and the release assembly is provided with a first groove and a second groove. The first groove is located on one side of the drive groove, and the second groove is located on the other side of the drive groove.

[0029] To explain the technical content and structural features of this utility model in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0030] Please see Figures 1 to 5 This utility model provides a safety lock drive structure 100 for an external storage box in a long-distance transport vehicle, including a housing 10, a handle 20, a limiting component 30, an operating component 40, a drive component 50, and a release component 60. The housing 10 has an inner surface 101 and an outer surface 102 disposed opposite to each other. A mounting post 11 and a limiting post 12 are protrudingly provided on the inner surface 101. The handle 20 is movably mounted on the outer surface 102 and connected to the limiting component 30 and the operating component 40 on the inner surface 101, enabling the entire structure to lock or unlock. The limiting component 30 is mounted on the inner surface 101 and connected to one end of the handle 20. The operating component 40 is mounted on the inner surface 101 and connected to the other end of the handle 20. The drive assembly 50 is mounted on the mounting post 11. One end of the drive assembly 50 is close to the limiting assembly 30 and abuts against the limiting post 12, while the other end of the drive assembly 50 is close to the operating assembly 40. A drive post 51 protrudes from the middle of the drive assembly 50. The unlocking assembly 60 has a through drive groove 61 in the middle. The drive groove 61 is fitted onto the drive post 51 and can move under the drive of the drive post 51. Both ends of the unlocking assembly 60 are rotatably connected to the housing 10. Specifically, the limiting assembly 30 rotates under the drive of the handle 20 and the key 23 until it abuts against the drive assembly 50 and limits the drive assembly 50 from both sides with the limiting post 12. Then, the end of the handle 20 away from the key 23 is pulled, so that the handle 20 drives the operating assembly 40 to move and push the drive assembly 50, causing the drive assembly 50 to slide between the limiting assembly 30 and the limiting post 12 and drive the unlocking assembly 60 to rotate and unlock.

[0031] Compared with the prior art, the safety lock drive structure 100 for the external storage box of the long-distance transport vehicle of this utility model has a compact and reasonable structure and is easy to operate. The safety lock drive structure 100 for the external storage box of the long-distance transport vehicle includes a housing 10, a handle 20, a limiting component 30, an operating component 40, a drive component 50, and a release component 60. The housing 10 has an inner surface 101 and an outer surface 102 that are arranged opposite to each other. A mounting post 11 is protruding on the inner surface 101, and a limiting post 12 is also protruding. The handle 20 is movably mounted on the outer surface 102 and its two ends are respectively connected to the limiting component 30 and the operating component 40 mounted on the inner surface 101. The drive component 50 is mounted on the mounting post 11 of the housing 10 and is located between the limiting component 30 and the operating component 40. One end of the drive component 50 is close to the limiting component 30 and abuts against the limiting post 12 from the side. A drive post 51 protrudes from the drive assembly 50, and a drive groove 61 is formed through the middle of the release assembly 60. The drive groove 61 is fitted onto the drive post 51, and both ends of the release assembly 60 are rotatably connected to the housing 10. Specifically, when the limiting assembly 30 rotates to abut against the drive assembly 50 and limits the drive assembly 50 from both sides with the limiting post 12, the handle 20 is pulled to drive the operating assembly 40 to push the drive assembly 50. The drive assembly 50 slides between the limiting assembly 30 and the limiting post 12, causing the release assembly 60 to rotate and release the lock. The safety lock drive structure 100 of the external storage box of the long-distance transport vehicle of this utility model is more stable. It requires the use of a key to rotate the limiting assembly 30 to a certain position before the handle 20 can be pulled to release the lock, making it safer and more reliable.

[0032] Please see Figures 1 to 5 In some optional embodiments, a first through groove 15 is provided on the housing 10, and a drive rod 21 is protruding from one end of the handle 20. The drive rod 21 passes through the first through groove 15 and is connected to the operating component 40. A receiving groove 211 is provided on the drive rod 21. The operating component 40 includes an operating member 401 and a first elastic member 402. The operating member 401 includes a driving end 41 and a rotating end 42. The driving end 41 of the operating member 401 passes through the receiving groove 211 and is located within the receiving groove 211. The first elastic member 402 is mounted on the rotating end 42, and the driving end 41 is constantly pressed against the receiving groove 211 by the first elastic member 402. Specifically, a mounting component 17 for mounting the operating member 401 is provided on the housing 10. The end of the operating member 401 away from the driving end 41 is the rotating end 42, which is rotatably mounted within the mounting component 17. The first elastic member 402 is mounted on the rotating end 42. Understandably, the drive end 41 is located in the receiving groove 211. Pulling the handle 20 causes the drive rod 21 to pry the drive end 41 to move, thereby causing the rotating end 42 to rotate around the mounting assembly 17, and causing the operating assembly 40 to push the drive assembly 50.

[0033] Please see Figures 1 to 5 and Figure 7 In some optional embodiments, a push block 421 is protruding from the rotating end 42. Pulling the handle 20 causes the drive rod 21 to pry the drive end 41, causing the rotating end 42 to drive the push block 421 to rotate, thereby causing the rotating push block 421 to push the drive assembly 50. On the other hand, a fixing block 422 is also protruding from the rotating end 42. A first elastic member 402 is sleeved on the rotating end 42 and fixed at one end to the mounting assembly 17, and at the other end to the fixing block 422. A hollow cavity is formed inside the rotating end 42, and a rotating shaft connected to the mounting assembly 17 is installed inside the cavity. The drive end 41 moves up and down under the prying of the drive rod 21 to drive the rotating end 42 to rotate around the mounting assembly 17, thereby causing the push block 421 to push the drive assembly 50. The rotating part has a constant tendency to return to its original position under the action of the first elastic member 402. When the force of pulling the handle 20 is removed, the first elastic element 402 drives the entire operating element 401 to reset, and makes the drive end 41 constantly abut against the drive groove 61 of the drive rod 21, which is simple and stable.

[0034] Please see Figures 1 to 8In some optional embodiments, the housing 10 has a second through slot 16, and one end of the handle 20 is connected to a connecting component 22. The connecting component 22 passes through the second through slot 16 and is connected to the limiting component 30. The limiting component 30 has a mounting hole 35 that mates with the connecting component 22. The handle 20 is driven by rotating the key 23, which in turn drives the limiting component 30 to rotate via the connecting component 22. The limiting component 30 includes a first limiting block 31 and a second limiting block 32, with the first limiting block 31 and the second limiting block 32 forming an integral structure. The driving component 50 includes a protruding positioning post 52, and there is an accommodating space 33 between the first limiting block 31 and the second limiting block 32 for accommodating the positioning post 52. The connecting component 22 is driven by the key 23 to rotate the limiting component 30, so that the positioning post 52 is positioned at different positions in the accommodating space 33. The positioning post 52 can abut against the first limiting block 31 or the second limiting block 32. When the positioning post 52 abuts against the first limiting block 31, the first limiting block 31 and the limiting post 12 limit the positioning post 52 from both sides. At this time, pulling the handle 20 will drive the drive rod 21 to pry the drive end 41 to move, thereby driving the rotating end 42 to rotate around the mounting assembly 17, and causing the operating assembly 40 to push the drive assembly 50, so that the drive assembly 50 slides linearly along the first limiting block 31 within the accommodating space 33. That is, the positioning post 52 is limited by the first limiting block 31 and the limiting post 12, so that the drive assembly 50 can only slide linearly, thereby driving the release assembly 60 to rotate, and then the release assembly 60 drives the release structure to release. It can be understood that the surface of the drive assembly 50 that mates with the mounting post 11 is provided with a mounting groove 53, which is installed on the mounting post 11 and is elongated. The stroke of the operating component 40 pushing the drive component 50 to slide along the first limit block 31 is the same as the stroke of the mounting groove 53 sliding along the mounting column 11.

[0035] On the other hand, when the limiting component 30 rotates to the point where the second limiting block 32 abuts against the positioning post 52, the second limiting block 32 and the limiting post 12 are on the same side. At this time, pulling the handle 20 and driving the rod 21 pry the driving end 41 to move, thereby driving the rotating end 42 to rotate around the mounting component 17. When the operating component 40 pushes the driving component 50, the driving component 50 rotates on its own and will not drive the release component 60 to rotate, thus failing to drive the release structure to release.

[0036] Please see Figures 1 to 6In some optional embodiments, the limiting component 30 further includes a second elastic member 34, and the first limiting block 31 is provided with a fixing hole 341 that cooperates with the second elastic member 34. The second elastic member 34 is used to keep the first limiting block 31 against the positioning post 52. That is, the second elastic member 34 applies a certain force to the first limiting block 31, so that when the operating component 40 pushes the driving component 50 to slide, the first limiting block 31 can keep limiting the driving component 50, so that the driving component 50 slides along the first limiting block 31.

[0037] Please see Figures 1 to 5 and Figure 10 In some optional embodiments, the housing 10 is provided with a first mounting portion 13 and a second mounting portion 14. The release assembly 60 has a first groove 62 and a second groove 63. The first groove 62 is located on one side of the drive groove 61, and the second groove 63 is located on the other side of the drive groove 61. The first groove 62 is mounted on the first mounting portion 13, and the second groove 63 is mounted on the second mounting portion 14. On the other hand, the release assembly 60 also includes a release member 64 and a third elastic member 65. The release member 64 is disposed on one side of the first groove 62 and connected to the release structure. The third elastic member 65 is disposed on the second mounting portion 14 and has a constant tendency to drive the release assembly 60 to reset. When the linearly sliding drive assembly 50 drives the release assembly 60 to rotate, the third elastic member 65 has a tendency to drive the entire release assembly 60 to reset. Both the drive groove 61 and the first groove 62 are elongated. The drive assembly 50 slides to allow the drive column 51 to slide along the drive groove 61 and drive the release assembly 60 to rotate around the second mounting portion 14. The first groove 62 slides along the first mounting portion 13 and drives the release member 64 to move, thereby causing the release structure to release. It can be understood that the release member 64 is connected to the release structure of the safety lock through the connecting hole 641. The action of the release member 64 can drive the release structure to release.

[0038] like Figures 1 to 10As shown, the safety lock drive structure 100 for the external storage compartment of a long-distance transport vehicle of this utility model has a compact and reasonable structure and is easy to operate. The safety lock drive structure 100 for the external storage compartment of a long-distance transport vehicle includes a housing 10, a handle 20, a limiting component 30, an operating component 40, a drive component 50, and a release component 60. The housing 10 has an inner surface 101 and an outer surface 102 disposed opposite to each other. A mounting post 11 is protrudingly disposed on the inner surface 101, and a limiting post 12 is also protrudingly disposed on the inner surface 101. The handle 20 is movably mounted on the outer surface 102, and its two ends are respectively connected to the limiting component 30 and the operating component 40 mounted on the inner surface 101. The drive component 50 is mounted on the mounting post 11 of the housing 10 and is located between the limiting component 30 and the operating component 40. One end of the drive component 50 is close to the limiting component 30 and abuts against the limiting post 12 from the side. A drive post 51 protrudes from the drive assembly 50, and a drive groove 61 is formed through the middle of the release assembly 60. The drive groove 61 is fitted onto the drive post 51, and both ends of the release assembly 60 are rotatably connected to the housing 10. Specifically, when the limiting assembly 30 rotates to abut against the drive assembly 50 and limits the drive assembly 50 from both sides with the limiting post 12, the handle 20 is pulled to drive the operating assembly 40 to push the drive assembly 50. The drive assembly 50 slides along the mounting post 11 through the mounting groove 53 between the limiting assembly 30 and the limiting post 12, and drives the release assembly 60 to rotate and release the lock. The safety lock drive structure 100 of the external storage box of the long-distance transport vehicle of this utility model is more stable. It requires the use of a key to rotate the limiting assembly 30 to a certain position before the handle 20 can be pulled to release the lock, making it safer and more reliable.

[0039] The above-disclosed examples are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall fall within the scope of the present utility model.
