[0061] Embodiment 1:
[0062] like Figure 1-Figure 5 as well as Fig.11 As shown, a vehicle lock body can be configured on a vehicle door to lock the vehicle door on the vehicle body. The vehicle lock body can be unlocked by an inner unlocking structure located on the inner side of the vehicle door, or by an outer unlocking structure located on the outer side of the vehicle door. Specifically, the inner unlocking structure is preferably but not limited to an inner handle 8A, and the outer unlocking structure is preferably but not limited to an outer handle 8B. For example, in addition to unlocking by selecting a handle, you can also choose to unlock by configuring a lock core and rotating the lock core. When the vehicle lock body is unlocked, the vehicle door can be opened from the vehicle body.
[0063] The vehicle lock body of this embodiment mainly comprises: a lock housing 1, a main lock tongue 2, a first movable member 3, an unlocking module 4 and a transmission module.
[0064] The lock housing 1 includes a lock housing body and a cover plate. The cover plate is arranged on the lock housing body. The cover plate is detachably fixed to the lock housing body by screws. When the cover plate is removed, the internal structure of the vehicle lock body can be displayed. The lock housing 1 of this embodiment is provided with a main lock tongue 2 and a first movable part 3. The main lock tongue 2 can be arranged in the lock housing 1 telescopically. When the main lock tongue 2 extends out of the lock housing 1, it can be locked into the vehicle body. When the main lock tongue 2 is retracted into the lock housing 1, the main lock tongue 2 is retracted from the vehicle body, which is convenient for opening the vehicle door. The first movable part 3 is movably arranged in the lock housing 1. The first movable part 3 can be arranged in the lock housing 1 telescopically up and down. During use, the first movable part 3 can be used to connect with other locking structures. For example, when the vehicle lock body is applied to a motorhome, the first movable part 3 can be connected with the auxiliary lock. The auxiliary lock can be unlocked by the movement of the first movable part 3.
[0065] The unlocking module 4 is movably arranged in the lock housing 1. The unlocking module 4 is movably connected to the first movable part 3 and is movably opposed to the main lock tongue 2. The unlocking module 4 can drive the main lock tongue 2 and the first movable part 3 to unlock the vehicle lock body. Whether the inner unlocking structure is unlocked or the outer unlocking structure is unlocked, the unlocking module 4 drives the main lock tongue 2 and the first movable part 3 to achieve unlocking. The unlocking module 4 includes a first unlocking part 41 and a second unlocking part 42. The first unlocking part 41 and the second unlocking part 42 are both movably opposed to the main lock tongue 2. The first unlocking part 41 and the second unlocking part 42 drive the main lock tongue 2 by rotating, wherein the first unlocking part 41 can be connected to the inner unlocking structure (such as the inner handle 8A). The rotation of the inner unlocking structure can directly drive the first unlocking part 41 to rotate.
[0066] The outer unlocking transmission module 5 is arranged in the lock housing 1 and is movably opposed to the unlocking module 4. The transmission module includes a rotatable rotating member 50. The rotating member 50 can be connected to the outer unlocking structure (such as the outer handle 8B). The outer unlocking module 4 transmits the action of the outer unlocking structure (such as the outer handle 8B) to the unlocking module 4 to realize the outer unlocking.
[0067] During use, when the inner unlocking structure (such as the inner handle 8A) drives the first unlocking member 41, so that the main lock tongue 2 retracts and the first movable member 3 moves: the first unlocking member 41 pushes against the main lock tongue 2, and the rotating member 50 does not move, so that the outer unlocking structure (such as the outer handle 8B) remains stationary. That is, when the inner unlocking structure drives the first unlocking member 41 to rotate, so that the main lock tongue 2 retracts and the rotating member 50 telescopically moves in the up and down directions to achieve the inner unlocking, the rotating member 50 does not move, that is, the outer unlocking structure (such as the outer handle 8B) connected to the rotating member 50 does not move and remains stationary. When the outer unlocking structure (such as the outer handle 8B) drives the rotating member 50, so that the main lock tongue 2 retracts and the first movable member 3 moves: the second unlocking member 42 pushes against the main lock tongue 2, and the first unlocking member 41 does not move, so that the inner unlocking structure remains stationary. That is, when the outer unlocking structure drives the rotating member 50 to rotate, the action is transmitted to the main lock tongue 2 and the first movable member 3 through the unlocking module 4, so that the main lock tongue 2 retracts and the rotating member 50 telescopically moves in the up and down directions. When the outer unlocking is realized, the first unlocking member 41 does not move, that is, the inner unlocking structure (such as the inner handle 8A) connected to the first unlocking member 41 does not move and remains stationary. In the process of inner unlocking and outer unlocking, the rotation center of the first unlocking member 41 during inner unlocking is not coaxial with the rotation center of the rotating member 50 during outer unlocking.
[0068] The vehicle lock body of this embodiment supports unlocking by the inner handle 8A and the outer handle 8B. The lock housing 1 is provided with a first unlocking member 41 and a second unlocking member 42. The first unlocking member 41 and the second unlocking member 42 can push the main lock tongue 2 separately to retract the main lock tongue 2. An outer unlocking transmission module 5 is provided to realize the transmission between the outer unlocking structure (such as the outer handle 8B) and the unlocking module 4, so that the outer unlocking structure (such as the outer handle 8B) can be kept away from the inner unlocking structure (such as the inner handle 8A) to avoid the coaxial arrangement of the two. The space on the side of the outer handle 8B is freed up for installing other reinforcement structures, and the thickness of the vehicle lock body can be saved. The outer handle 8B does not need to be set as a convex shape to prevent people from hitting the handle, and it is also convenient to set the outer handle 8B as a hidden door handle. During use, when the inner handle 8A is operated to unlock, the outer handle 8B does not move; when the outer handle 8B is operated to unlock, the inner handle 8A does not move. The two actions are independent and do not interfere with each other. The movement modes of the inner and outer handles 8B can be designed to be completely different. For example, the outer side can be set to electric unlocking, and the inner side can be mechanically unlocked, etc. The design of the vehicle lock body in this embodiment has many options and a high degree of design freedom.
[0069] like Figure 3-Figure 9 As shown, the unlocking module 4 of this embodiment includes, in addition to the first unlocking member 41 and the second unlocking member 42, a toggle member 43, which is movably connected to the first unlocking member 41, and the toggle member 43 is movably connected to the first movable member 3, and can drive the first movable member 3. Specifically, a boss protrudes from the toggle member 43 toward the first movable member 3, and a long groove is provided on the first movable member 3 in the left-right direction, and the boss on the toggle member 43 extends into the long groove. When the toggle member 43 rotates, the boss can push the first movable member 3, so that the first movable member 3 can telescope in the up-down direction.
[0070] The toggle member 43 and the second unlocking member 42 are both sleeved on the first unlocking member 41, and the second unlocking member 42 can rotate relative to the first unlocking member 41. The first unlocking member 41 is rotatably arranged in the lock housing 1, and the first unlocking member 41 is provided with a first protrusion 410. The toggle member 43 is provided with a first slide groove 430, and the first protrusion 410 is movably arranged in the first slide groove 430. When the first unlocking member 41 rotates and the first protrusion 410 slides to the end of the first slide groove 430, the first unlocking member 41 can drive the toggle member 43. When unlocking from the inside, the first unlocking piece 41 just rotates to push the main lock tongue 2 to retract, and the first protrusion 410 in the first unlocking piece 41 slides along the first slide groove 430 on the toggle piece 43. At this time, the first unlocking piece 41 will not drive the toggle piece 43; as the first unlocking piece 41 continues to rotate, the first protrusion 410 moves to the end of the first slide groove 430, and the continued rotation of the first unlocking piece 41 will drive the toggle piece 43 to rotate through the first protrusion 410, and the toggle piece 43 drives the first movable piece 3 to telescope. The cooperation of the first protrusion 410 and the first slide groove 430 can realize the successive movement of the main lock tongue 2 and the first movable piece 3. When unlocking from the outside, the action of the rotating member 50 is transmitted to the second unlocking member 42, and the second unlocking member 42 pushes the main lock tongue 2 to retract. At this time, the toggle member 43 will not move immediately. As the rotating member 50 continues to rotate, the toggle member 43 will be driven through the first rotating bracket 51, and the toggle member 43 will rotate, causing the first movable member 3 to telescope.
[0071] The outer unlocking transmission module 5 of this embodiment includes not only the rotating member 50, but also mainly includes: a first rotating bracket 51, a second rotating bracket 52 and a third rotating bracket 53. The first rotating bracket 51 is sleeved on the rotating member 50 and movably connected with the rotating member 50, and the first rotating bracket 51 and the toggle member 43 are movably opposed. During use, the rotating member 50 can drive the toggle member 43 through the first rotating bracket 51. Among them, a second slide groove 510 is provided on the first rotating bracket 51, and a second protrusion 501 is provided on the rotating member 50. The second protrusion 501 is movably arranged in the second slide groove 510. When the rotating member 50 rotates and the second protrusion 501 slides to the end of the second slide groove 510, the rotating member 50 can drive the first rotating bracket 51, and then drive the toggle member 43.
[0072] The second rotating bracket 52 is sleeved on the rotating member 50, and the second rotating bracket 52 is fixedly connected to the rotating member 50. Specifically, a card slot is provided on the second rotating bracket 52, and a card block adapted thereto is provided on the rotating member 50. The card block is stuck in the card slot. Through the card block and the card slot, torque can be transmitted between the rotating member 50 and the second rotating bracket 52. The third rotating bracket 53 is rotatably arranged between the second rotating bracket 52 and the second unlocking member 42, and is respectively movably opposed to the two. The rotating member 50 can drive the second unlocking member 42 through the second rotating bracket 52 and the third rotating bracket 53, so that when unlocking from the outside, the lock tongue can be retracted by transmitting power to the second unlocking member 42, without the need to drive the lock tongue to retract through the first unlocking member 41.
[0073] More specifically, the first rotating bracket 51 extends a transmission arm 511 toward the side close to the toggle member 43, and a push column 512 is disposed at the end of the transmission arm 511. The push column 512 can be arranged in an integrated or split manner with the first rotating bracket 51. The toggle member 43 is provided with an opening slot 431, and the push column 512 extends into the opening slot 431. When the first rotating bracket 51 pushes the side wall of the opening slot 431 through the push column 512, the toggle member 43 can be driven to rotate. That is, when the rotating member 50 drives the first rotating bracket 51 to rotate, the first rotating bracket 51 pushes the toggle member 43 through the push column 512, so that the toggle member 43 rotates. A first push arm 521 extends from the second rotating bracket 52, a second push arm 531 and a third push arm 532 extend from the third rotating bracket 53, and a fourth push arm 420 extends from the second unlocking member 42. The first push arm 521 and the second push arm 531 are movably opposed to each other, and the third push arm 532 and the fourth push arm 420 are movably opposed to each other. When the rotating member 50 drives the second rotating bracket 52 to rotate, the first push arm 521 on the second rotating bracket 52 pushes the second push arm 531 on the third rotating bracket 53, and the third rotating bracket 53 pushes the fourth push arm 420 on the second unlocking member 42 through the third push arm 532, so that the second unlocking member 42 rotates, and the second unlocking member 42 pushes the main lock tongue 2, so that the main lock tongue 2 retracts.
[0074] In actual use, when unlocking through the inner unlocking structure (such as the inner handle 8A): the inner unlocking structure is rotated to rotate the first unlocking member 41, and the first unlocking member 41 pushes the main lock tongue 2, and the main lock tongue 2 retracts. At this time, the first protrusion 410 on the first unlocking member 41 slides along the first slide groove 430 in the toggle member 43, and the toggle member 43 does not move. As the first unlocking member 41 continues to rotate, the first protrusion 410 on the first unlocking member 41 reaches the end of the first slide groove 430, and the first unlocking member 41 continues to rotate, which will drive the toggle member 43 to rotate, and the toggle member 43 drives the first movable member 3 to telescope until the main lock tongue 2 is completely retracted and the first movable member 3 is completely telescoped. Since the toggle member 43 rotates during this process, the toggle member 43 will drive the first rotating bracket 51 to rotate. Since the first rotating bracket 51 is provided with a second slide groove 510, when the toggle member 43 drives the first rotating bracket 51 to rotate, the second slide groove 510 moves relative to the second protrusion 501, and the second protrusion 501 does not move, that is, the rotating member 50 does not move. Therefore, the outer unlocking structure (such as the outer handle 8B) will not move, ensuring that the inner unlocking does not affect the outer unlocking structure.
[0075] In actual use, when unlocking through the outer unlocking structure (such as the outer handle 8B): rotate the outer unlocking structure to rotate the rotating member 50, the rotating member 50 drives the second rotating bracket 52 to rotate, the second rotating bracket 52 drives the third rotating bracket 53 to rotate, the third rotating bracket 53 drives the second unlocking member 42 to rotate, the second unlocking member 42 pushes the main lock tongue 2 to retract the main lock tongue 2, and the rotating member 50 rotates at this time to make the second protrusion 501 slide along the second slide groove 510, so the first rotating bracket 51 will not move, and the rotation of the rotating member 50 continues. , the second protrusion 501 reaches the end of the second sliding groove 510, and the continued rotation of the rotating member 50 will drive the first rotating bracket 51 to rotate, thereby causing the toggle member 43 to rotate, and the toggle member 43 drives the first movable member 3 to perform telescopic movement. When the toggle member 43 rotates, the first sliding groove 430 on the toggle member 43 moves relative to the first protrusion 410 on the first unlocking member 41, and the first protrusion 410 does not move, that is, the first unlocking member 41 does not move, so the inner unlocking structure (such as the inner handle 8A) will not move, ensuring that the outer unlocking does not affect the inner unlocking structure.
[0076] like Figure 3 and Fig.10As shown, the vehicle lock body of this embodiment also includes a reset torsion spring 20, a safety lock tongue and a locking module 7. One end of the reset torsion spring 20 is against the main lock tongue 2, and the other end is against the lock shell 1. The elastic force of the reset torsion spring 20 makes the main lock tongue 2 have a tendency to move in the outward extension direction, ensuring that the main lock tongue 2 can be reset after unlocking. The safety lock tongue can be used in conjunction with the safety switch in the vehicle lock body. When the safety lock tongue is not retracted into the lock shell 1, the locking module 7 cannot lock the first movable part 3 and the main lock tongue 2, so as to avoid the situation of wrong locking in the open door state. Closing the door is easy to break the main lock tongue 2 or damage the car door. When the car door is closed, the safety lock tongue is forced to retract into the lock shell 1, and the locking module 7 can lock the first movable part 3 and the main lock tongue 2 at this time.
[0077] Optionally, the locking module 7 of this embodiment can adopt a mechanical locking mechanism or an electronic locking mechanism. Specifically, the locking module 7 of this embodiment mainly includes a motor 70, a first locking block 71 and a second locking block 72. The motor 70 is used as a power member for electronic locking and electronic unlocking. The first locking block 71 can lock the main lock tongue 2, and the second locking member can lock the first movable member 3. The detailed structure of the locking module 7 of this embodiment can be found in the patent with publication number CN220565893U. It adopts a combination of mechanical and electronic locking, and the locking module 7 can be purely mechanically unlocked or purely electronically unlocked, or a combination of mechanical and electronic unlocking.
[0078] Optionally, the vehicle lock of this embodiment further includes a second movable member 6 and a driving member 60 movably connected to the second movable member 6. The second movable member 6 is arranged in the lock housing 1 so as to be telescopically movable up and down. The second movable member 6 can be connected to other locking structures. For example, similar to the first movable member 3, the second movable member 6 can also be used to connect the secondary lock, and the secondary lock can be unlocked by the telescopic movement of the second movable member 6 up and down. The driving member 60 is rotatably arranged in the lock housing 1. The driving member 60 can be connected to the handle. By turning the handle, the driving member 60 rotates, thereby driving the second movable member 6 to telescopically move.
[0079] Embodiment 2:
[0080] In order to apply the vehicle lock body in the first embodiment to the RV, the RV lock of this embodiment is arranged on the door of the RV and can lock the door of the RV on the RV. In addition, an inner handle 8A is arranged on the inner side of the door of the RV and an outer handle 8B is arranged on the outer side of the door of the RV. The operator can open the RV lock and open the door through the inner handle 8A; the operator can also open the RV lock and open the door through the outer handle 8B. The premise of unlocking is that the locking module 7 on the RV lock has unlocked the main lock tongue 2 and the first movable part 3. During use, when the inner handle 8A drives the first unlocking part 41 to retract the main lock tongue 2 and telescopically move the first movable part 3: the first unlocking part 41 pushes the main lock tongue 2, and the rotating part 50 does not move, so that the outer handle 8B remains stationary. When the outer handle 8B drives the rotating member 50 to retract the main locking tongue 2 and telescope the first movable member 3, the second unlocking member 42 pushes the main locking tongue 2 and the first unlocking member 41 does not move, so that the inner handle 8A remains stationary.
[0081] During use, referring to the prior art cited in the background technology, the RV lock of this embodiment can also be configured with a secondary lock.
[0082] In this solution, the two actions of inside unlocking and outside unlocking are independent and do not interfere with each other. There are many design options and a high degree of design freedom. The outer handle 8B and the inner handle 8A do not need to be set coaxially. The space on the side of the outer handle 8B can be freed up to install other reinforcement structures and save the thickness of the lock body. The outer handle 8B does not need to be set to be convex, which can prevent the user from hitting the outer handle 8B and avoid it from interfering with other structures.
