Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lock, in particular to a door inside and outside double unlocking type RV lock. BACKGROUND

[0002] With the continuous improvement of living standards and the continuous development of social civilization, the RV life form gradually appears, and the RV lock is indispensable on the RV. The existing RV lock can usually only be unlocked from the outside by inserting a key, and cannot be directly opened inside the door. When an emergency occurs (such as a fire inside the RV, a fault in the external lock hole, a lost key, or a person accidentally locked in the vehicle), the internal personnel cannot quickly unlock and escape, which poses a serious safety hazard. SUMMARY

[0003] In view of the deficiencies of the prior art, the present application is convenient for safe unlocking from the inside of the RV in an emergency.

[0004] To achieve the above object, the technical scheme of the present application is as follows: a door inside and outside double unlocking type RV lock, comprising a lock body with an installation cavity processed on the outside, a lock cover placed in the installation cavity, a lock tongue located on the inside of the lock body, one end of the lock cover is fixedly connected with a first rotating shaft, both ends of the first rotating shaft are rotatably inserted into the lock body, one end of the lock tongue is linked with the first rotating shaft, the other end of the lock cover is installed with a main lock cylinder, a locking mechanism linked with the main lock cylinder is arranged between the lock cover and the lock body, an inside unlocking hole corresponding to the position of the main lock cylinder is processed on the inside of the lock body, an inside unlocking assembly capable of unlocking or locking the main lock cylinder is installed at the inside unlocking hole, a torsion spring automatically lifting the lock cover after unlocking the main lock cylinder is sleeved on the first rotating shaft.

[0005] When the door is unlocked from outside, the outside key is inserted into the main lock cylinder and rotated to drive the locking mechanism to release, and the torsional spring automatically lifts the lock cover to swing around the first rotating shaft towards the direction away from the lock body. The lock bolt is synchronized with the lock cover to disengage from the door frame to complete the regular unlocking. After reversing the key, the lock bolt is reset by pressing the lock cover to achieve locking. When the door is unlocked from inside, the inside unlocking assembly controls the rotation of the main lock cylinder to trigger the locking mechanism to release, and the lock cover swings around the first rotating shaft and the lock bolt is synchronized to disengage from the door frame to quickly complete the inside unlocking. The inside and outside unlocking processes are linked by pure mechanical structure. The design adds a linkage channel between the inside unlocking assembly and the main lock cylinder, providing an independent and reliable unlocking path for internal personnel in the event of external lock hole failure, key loss or emergency escape scenarios, effectively solving the safety hazards of existing house and car locks that can only be unlocked from the outside, and meeting the high requirements of emergency escape. At the same time, the main lock cylinder, locking mechanism and inside unlocking assembly are integrated into the lock body, eliminating the need for additional escape windows or complex electronic systems, simplifying the structure design of house and car doors, and avoiding the risk of electronic component aging failure with pure mechanical structure, ensuring long-term stability and reliability. In addition, the inside unlocking assembly is hidden inside the lock body and cannot be easily damaged, ensuring the convenience of emergency unlocking and not reducing the anti-theft performance of the lock, achieving a balance between function and safety, improving the safety, reliability and practicality of the house and car lock without additional cost, and suitable for various house and car lock scenarios. The elastic potential energy stored in the torsional spring enables the lock cover to automatically and quickly pop open a distance or completely open in the opening direction (usually outward rotation) under the action of the torsional spring at the moment the locking mechanism is released (the barb is disengaged from the hook groove), driving the lock bolt to retract. This greatly facilitates the user, especially in an emergency, without having to exert force to pull the lock cover, the unlocked door can be easily pushed open; on the other hand, the automatic pop-up action also provides a clear feedback of successful unlocking. The two torsional arms of the torsional spring press against the lock body and the lock cover, respectively, with simple and direct structure, high torsional force transmission efficiency, and easy assembly and pre-tightening force adjustment.

[0006] Further, the inside unlocking assembly includes a rotating positioning sleeve and an inside unlocking key. The rotating positioning sleeve is rotatably positioned in the inside unlocking hole. A rectangular linkage hole is formed in the middle of the rotating positioning sleeve and is adapted to the outer periphery of the inside unlocking key. When the inside unlocking key is inserted into the main lock cylinder along the rectangular linkage hole, rotating the inside unlocking key can simultaneously drive the main lock cylinder to rotate.

[0007] The rotating positioning sleeve can be rotatably positioned at the inner unlocking hole, playing the dual role of bearing and guide seat, ensuring that the inner unlocking key can only move along the predetermined path (i.e. axial sliding and circumferential rotation), smooth operation and accurate positioning. The design of the rectangular linkage hole is matched with the outer peripheral shape of the inner unlocking key (such as a rectangular rod), and this non-circular cross-section torque transmission method avoids key slipping in the hole, ensuring that when the inner key is rotated, the torque can be transmitted to the main lock cylinder 100% to achieve reliable unlocking or locking action. The structure has high standardization, and the inner unlocking key can be separately stored as a car tool, used in emergency, improving safety. As a preferred way, the rod part of the inner unlocking key is a flat square rod that closely matches the rectangular linkage hole, and the end inserted into the main lock cylinder is processed with a tooth shape matched with the main lock cylinder. When it needs to be unlocked from the inside, the user pushes the inner unlocking key forward until the tooth-shaped end is fully inserted into the key hole of the main lock cylinder and reaches the bottom, and rotating the key handle can drive the rotating positioning sleeve and the main lock cylinder to rotate together, completing the unlocking action. The design of the insertion depth makes the key only transmit torque when it is fully in place, preventing operation failure or damage due to incomplete insertion.

[0008] Further, the inner unlocking key is linked with an elastic reset member that can drive the inner unlocking key to axially reset along the inner unlocking hole, a longitudinal strip-shaped hole is formed on the inner unlocking key, the elastic reset member is a first spring installed at the longitudinal strip-shaped hole, a transverse mounting hole corresponding to the longitudinal strip-shaped hole is processed on the rotating positioning sleeve, a limiting member is fixed at the transverse mounting hole, one end of the first spring is pressed against the limiting member, and the other end of the first spring is pressed against the inner end of the longitudinal strip-shaped hole.

[0009] The scheme adds an automatic reset function to the inner unlocking key, greatly optimizing user experience and safety. The setting of the elastic reset member (first spring) enables the inner unlocking key to automatically exit the main lock cylinder and retract to the initial position under the action of the force of the first spring after the user completes the inner unlocking operation and releases the inner unlocking key. This avoids the inner unlocking key being inserted in the inner channel for a long time, which may cause obstruction, rust, or accidental impact damage. On the other hand, the automatic retraction of the key also makes it more concealed, reducing the risk of being peeped or manipulated by tools through the inner unlocking hole. The cooperation of the longitudinal strip-shaped hole, the transverse mounting hole, and the limiting member ingeniously integrates the installation and limiting of the first spring between the inner unlocking key and the rotating positioning sleeve, with a compact structure and without occupying additional space. As a preferred mode, the limiting member can be a pin transversely passing through the transverse mounting hole of the rotating positioning sleeve, with both ends of the pin fixed on the lock body or the rotating positioning sleeve. The first spring is sleeved on the pin, with one end abutting against the middle part of the pin or a washer fixed on the pin, and the other end abutting against the end face of the deep part of the longitudinal strip-shaped hole of the inner unlocking key. When the inner unlocking key is pushed inward, the key slides along the strip-shaped hole and compresses the first spring; after the key is released, the released elastic force of the compressed first spring pushes the key to slide reversely along the strip-shaped hole until the outer end of the strip-shaped hole on the key contacts with the pin for limiting, at which time the tooth-shaped end of the key is completely separated from the main lock cylinder, completing the automatic reset.

[0010] Further, the locking mechanism includes an unlocking member, a manual unlocking groove is processed in the middle part of the lock cover, the upper end of the unlocking member extends to the manual unlocking groove, the middle part of the unlocking member is rotatably positioned on the lock cover by setting a second rotating shaft, the lower end of the unlocking member is processed with a barb, the inner side of the lock body is processed with a hook groove corresponding to the barb, the lower end of the unlocking member is also provided with a stop block extending to one side of the main lock cylinder, the lower end of the main lock cylinder and located on the outer peripheral surface is processed with a give-way groove, the locking mechanism further includes a pushing structure, when the give-way groove corresponds to the hook groove, the pushing structure can push the stop block to swing upward.

[0011] The cooperation of the barb and the hook groove on the lock body constitutes the most direct mechanical locking point between the lock cover and the lock body, with a solid structure and strong impact resistance. The cooperation of the stop block and the give-way groove on the main lock cylinder is the key, which realizes the linkage of the lock cylinder state and the mechanical locking state: only when the main lock cylinder is rotated to the correct unlocking position (the give-way groove is turned to be opposite to the stop block), the stop block can be pushed to swing, thereby releasing the barb; if the main lock cylinder is in the locking position, the complete outer peripheral surface will block the swing of the stop block, and the barb cannot be separated from the hook groove, thereby the lock can safely lock the door, indicating safety. The design of the pushing structure enables the unlocking action to be automatic or semi-automatic, improving the operation convenience.

[0012] Further, the inner side of the lock body is processed with a positioning hole corresponding to the stop block, the pushing structure includes a pushing rod inserted into the positioning hole, the outer periphery of the pushing rod is sleeved with a second spring, the inner side of the positioning hole is provided with a first step, the lower end of the second spring is pressed against the first step, the inner side of the positioning hole is further provided with a second step, and the outer periphery of the pushing rod is provided with a stop ring.

[0013] The cooperation of the pushing rod and the positioning hole ensures the linearity and accuracy of the pushing action, and ensures that the force can accurately act on the stop block. The first step is used to support the lower end of the spring, and the second step cooperates with the stop ring on the pushing rod to jointly limit the initial position and the maximum stroke of the pushing rod when it is not triggered externally, preventing it from being pushed out or falling off excessively. When the door is unlocked from the inside, the inner unlocking key is pressed to drive the main lock cylinder to rotate to the position recess corresponding to the stop block, the pushing rod is pressed by hand, and the unlocking part is pushed to swing, so that the barb is separated from the hook groove, and the lock cover can be rotated to achieve unlocking. After the hand is released, the second spring automatically drives the pushing rod to reset.

[0014] Further, the end of the rotating positioning sleeve towards the main lock cylinder is processed with a wedge-shaped block, the wedge-shaped block is opposite to the position recess, the side of the stop block towards the main lock cylinder is provided with an arc surface, the top of the wedge-shaped block is connected with a spherical positioning part, and the wedge-shaped block and the spherical positioning part jointly constitute a pushing structure.

[0015] When the inner unlocking key is used from the inside, the inner unlocking key is inserted into and rotates the main lock cylinder. Since the inner unlocking key and the rotating positioning sleeve are linked through the rectangular hole, the rotating positioning sleeve also rotates synchronously. The wedge-shaped block processed at the end of the rotating positioning sleeve rotates (the position recess rotates to correspond to the stop block), and the inclined surface or top surface of the wedge-shaped block gradually approaches and contacts the arc surface on the stop block. With continuous rotation, the wedge-shaped block will "climb" or "squeeze" along the arc surface of the stop block, and the radial component force generated in this process will push the stop block to move away from the main lock cylinder (i.e. upwards), thereby prying the unlocking part to rotate and releasing the barb. The arrangement of the spherical positioning part helps to form smooth point contact with the arc surface, reduces friction, and makes the action smoother. This scheme completely synchronizes and integrates the internal unlocking action (rotating the key) and the action of triggering the locking mechanism to release (wedge-shaped block pushing), with clear logic and coherent operation.

[0016] Further, the lock tongue includes a lock tongue body and symmetrical connection swing arms arranged on both sides of the lock tongue body, one end of the connection swing arm is fixedly connected with the lock tongue body through a screw, and the other end of the connection swing arm is fixedly connected with the first rotating shaft through a screw.

[0017] The split type lock tongue body and the connecting swing arm are connected through screws, so that the processing and assembly of each part are more flexible and simple, and the mold cost and processing difficulty are reduced. The lock tongue body can be made of high-strength material alone to enhance the shear capacity. The two symmetrical connecting swing arms firmly connect the lock tongue body and the first rotating shaft together, forming a stable double support transmission structure, which can uniformly transmit torque and prevent the lock tongue from being stuck on one side. The first rotating shaft is supported at both ends on the lock body, constituting the core load-bearing shaft of the entire rotating part, which has good structural rigidity.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application. EMBODIMENT

[0022] Embodiment one: as shown in the door inner unlockable type recreational vehicle mechanical lock, comprising a lock body 1, a lock cover 2, a lock bolt 3, a first rotating shaft 4, a main lock core 5, a locking mechanism, a door inner unlocking assembly, and a torsional spring 8. Figures 1 to 4 The outer side of the lock body 1 is machined with a mounting cavity for accommodating other components. The lock cover 2 is placed in the mounting cavity, and one end thereof is rotatably connected with the lock body 1 through the first rotating shaft 4. Specifically, one end of the lock cover 2 is fixedly connected with the first rotating shaft 4, and the two ends of the first rotating shaft 4 are rotatably inserted into the pre-set shaft holes of the lock body 1, so as to realize the swing of the lock cover 2 relative to the lock body 1. The lock bolt 3 is located on the inner side of the lock body 1, and one end thereof is linked with the first rotating shaft 4, so that the swing of the lock cover 2 can drive the lock bolt 3 to move synchronously, thereby realizing the buckling or disengagement with the door frame. As a preferred embodiment, the lock bolt 3 comprises a lock bolt body 31 and two connecting swing arms 32 symmetrically arranged on both sides of the lock bolt body 31. One end of each of the two connecting swing arms 32 is fixedly connected with the lock bolt body 31 through a screw, and the other end thereof is also fixedly connected with the first rotating shaft 4 through a screw. This split design facilitates processing and assembly, and the double support structure makes the stress more uniform.

[0023]

[0024] ​The other end of the lock cover 2 is provided with a main lock cylinder 5, which is a conventional blade lock cylinder structure and can be operated by an external key. A locking mechanism linked with the main lock cylinder 5 is arranged between the lock cover 2 and the lock body 1, for locking the lock cover 2 in the closed position. A torsional spring 8 is sleeved on the first rotating shaft 4, and the two torsional arms of the torsional spring 8 are respectively pressed against the lock body 1 and the lock cover 2, and pre-store elastic potential energy. When the locking mechanism is released, the torsional spring 8 can automatically drive the lock cover 2 to pop up around the first rotating shaft 4 towards the direction away from the lock body 1, providing automatic opening and clear unlocking feedback.

[0025] An inner unlocking hole 12 corresponding to the position of the main lock cylinder 5 is processed on the inner side of the lock body 1. An inner door unlocking assembly is arranged at the inner unlocking hole 12, which can be operated from the inside of the vehicle to unlock or lock the main lock cylinder 5. The inner door unlocking assembly includes a rotating positioning sleeve 71 and an inner unlocking key 72. The rotating positioning sleeve 71 is rotatably positioned at the inner unlocking hole 12, and functions as a guide seat. A rectangular linkage hole 711 is formed in the middle of the rotating positioning sleeve 71. The rod part of the inner unlocking key 72 is a flat square rod matched with the rectangular linkage hole 711, and the insertion end is processed with a tooth shape matched with the internal structure of the main lock cylinder 5. When the inner unlocking key 72 is slid along the rectangular linkage hole 711 and completely inserted into the key hole of the main lock cylinder 5, rotating the inner unlocking key 72 can transmit torque through the rectangular linkage hole 711, synchronously driving the main lock cylinder 5 to rotate, and realizing reliable internal unlocking or locking.

[0026] Further, to realize automatic reset of the inner unlocking key 72, a longitudinal strip-shaped hole 721 is formed on the inner unlocking key 72. A transverse mounting hole 712 corresponding to the longitudinal strip-shaped hole 721 is processed on the rotating positioning sleeve 71. A pin serving as a limiting member 713 is fixedly arranged at the transverse mounting hole 712. A first spring 714 serving as an elastic reset member is arranged in the longitudinal strip-shaped hole 721. One end of the first spring 714 is pressed against the limiting member 713, and the other end is pressed against the inner end face of the longitudinal strip-shaped hole 721. When the inner unlocking key 72 is pushed inward, the first spring 714 is compressed; after being released, the elastic force of the first spring 714 drives the inner unlocking key 72 to automatically retract, so that the tooth-shaped end is separated from the main lock cylinder 5, and returns to the initial concealed position.

[0027] The locking mechanism comprises an unlocking member 61. A manual unlocking slot is formed in the middle of the lock cover 2, and the upper end of the unlocking member 61 extends to the slot and can be pressed manually. The middle of the unlocking member 61 is rotatably positioned on the lock cover 2 by means of a second rotating shaft 62. The lower end of the unlocking member 61 is provided with a barb 611, and the inner side of the lock body 1 is provided with a hook groove 13 corresponding to the barb 611. When the lock cover 2 is closed, the barb 611 is buckled into the hook groove 13 to achieve mechanical locking. The lower end of the unlocking member 61 is also provided with a stop block 612 extending towards the side of the main lock cylinder 5. Correspondingly, a recess 51 is formed on the outer circumferential surface of the lower end of the main lock cylinder 5.

[0028] The inner side of the lock body 1 is provided with a positioning hole 11 corresponding to the stop block 612. A pushing structure 63 of the locking mechanism is installed at the positioning hole 11. The pushing structure 63 comprises a pushing rod 631 and a second spring 632. The pushing rod 631 is inserted into the positioning hole 11, and the outer periphery of the pushing rod 631 is sleeved with the second spring 632. The inner side of the positioning hole 11 is provided with a first step, and the lower end of the second spring 632 is pressed against the first step. The inner side of the positioning hole 11 is also provided with a second step, and the outer periphery of the pushing rod 631 is provided with a stop ring 633 for limiting the maximum stroke of the pushing rod 631. In the natural state, the head of the pushing rod 631 is reset by the elastic force of the second spring 632. When the main lock cylinder 5 (whether by an external key or an internal key) is rotated to the correct unlocking position, so that the recess 51 on the outer circumferential surface of the main lock cylinder 5 is rotated to be opposite to the stop block 612, an external force (such as finger pressing) can be applied to the pushing rod 631 to make it move inwardly against the elastic force of the second spring 632. The head of the pushing rod 631 enters the area of the recess 51 and abuts against the stop block 612, pushing the stop block 612 to swing upwardly. Since the unlocking member 61 rotates around the second rotating shaft 62, the upward swing of the stop block 612 drives the barb 611 to swing downwardly, so that the barb 611 is separated from the hook groove 13 of the lock body 1, and the locking of the lock cover 2 is released. Subsequently, under the action of the torsional spring 8, the lock cover 2 is automatically opened and the bolt 3 is retracted, completing the unlocking.

[0029] The working principle of the first embodiment is as follows: When unlocking from the outside, an external key is inserted into the main lock cylinder 5 and rotated to the unlocking position (the recess 51 is aligned with the stop block 612), and then the unlocking member 61 is pressed from the outside. The unlocking member 61 rotates around the second rotating shaft 62, and the upward swing of the stop block 612 drives the barb 611 to swing downwardly, so that the barb 611 is separated from the hook groove 13 of the lock body 1, and the locking of the lock cover 2 is released. Reverse rotation of the key and pressing of the lock cover 2 can make the bolt 3 reset and buckle, and the barb 611 is inserted into the hook groove 13.

[0030] When unlocking from the inside, press the inner unlocking key 72 and push it all the way forward until its toothed end is fully inserted into the main lock cylinder 5. Then, turn the handle of the inner unlocking key 72 to rotate the main lock cylinder 5 to the unlock position. Next, press the push rod 631 to push the stop block 612, releasing the barb 611. After the locking mechanism is released, the torsion spring 8 drives the lock cover 2 to spring open, completing the quick unlocking from the inside. After releasing the inner unlocking key 72, it automatically returns to its original position under the action of the first spring 714.

[0031] Example 2: Figures 5 to 7 As shown, the main difference between Embodiment 2 and Embodiment 1 lies in the different pushing structure 63. The pushing structure 63 in Embodiment 2 is as follows: a wedge-shaped block 73 is machined on the end of the rotating positioning sleeve 71 facing the main lock cylinder 5. This wedge-shaped block 73 is positioned opposite to the clearance groove 51 on the main lock cylinder 5. A spherical positioning element 74 is connected to the top of the wedge-shaped block 73. The wedge-shaped block 73 and the spherical positioning element 74 together constitute the pushing structure 63 in this embodiment.

[0032] Unlocking from the inside: The inside unlocking key 72 is pressed by hand until its toothed end is fully inserted into the main lock cylinder 5. Since the inside unlocking key 72 and the rotating positioning sleeve 71 are linked through the rectangular linkage hole 711, when the handle of the inside unlocking key 72 is rotated, it simultaneously drives the rotating positioning sleeve 71 and the wedge block 73 fixed thereon to rotate together. The rotation of the inside unlocking key 72 also simultaneously drives the main lock cylinder 5 to rotate to the unlock position, causing the clearance groove 51 on its outer circumference to rotate and align with the stop block 612. As the rotating positioning sleeve 71 rotates, the wedge block 73 gradually approaches the stop block 612. The inclined surface (or top surface) of the wedge block 73 contacts the arc surface 6121 of the stop block 612. Continuing to rotate the key, the wedge block 73 "climbs" along the arc surface 6121, generating a radially outward thrust. This thrust, through the point contact between the spherical positioning element 74 and the arc-shaped surface 6121, smoothly pushes the stop block 612 away from the main lock cylinder 5 (i.e., upward). The upward swing of the stop block 612 causes the entire unlocking element 61 to rotate around the second pivot 62, causing the lower end of its barb 611 to swing downward, thereby disengaging from the hook groove 13 of the lock body 1 and releasing the lock. Subsequently, the torsion spring 8 quickly drives the lock cover 2 to spring open, causing the bolt 3 to retract, completing a continuous internal unlocking operation. Throughout the process, the action of turning the key directly and synchronously triggers the release of the locking mechanism, without the need for additional pressing steps.

[0033] The procedure for unlocking the door from the outside is the same as in Example 1, so it will not be described again here.

[0034] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
