Description

Technical Field

[0001] This invention relates to the field of RV locks, and particularly to an RV lock clutch assembly. Background Technology

[0002] Existing RV locks only have one set of locking linkage mechanism, which is directly linked to the handle. There is no internal safety module in the RV lock, so opening the door only requires disengaging this single mechanism. This disengagement is extremely unsafe, as the vehicle's infotainment system cannot fully lock the door while driving; simply moving the inner handle allows the locking linkage mechanism to open the door from the inside. For example, the helicopter sliding door locking mechanism (application number 202010730518.6) operates by using an outer or inner handle to drive the lock cylinder shaft, which in turn drives a star-shaped component. This component drives a large adapter, which in turn drives a small adapter. The small adapter, through upper and lower wire rope assemblies, disengages the lock hooks in the upper and lower lock box assemblies from the lock cylinder, opening the locking mechanism. Without any safety module, it is easy to accidentally unlock the lock by touching the handle, or the lock may be easily opened by vibration during the operation of the aircraft or vehicle.

[0003] In view of the above problems, the present invention provides a RV lock clutch assembly, and this case arises from this invention. Summary of the Invention

[0004] This invention provides a RV lock clutch assembly, which has the function of cutting off or transmitting the external force transmitted from the inner or outer handle to the locking linkage assembly, making the lock more secure; specifically, this invention is achieved through the following technical solution:

[0005] A RV lock clutch assembly includes a latch plate, a shaft fork, a clutch block pull plate, a clutch block, a spring, and a lever plate. The clutch block pull plate has a clutch block groove, and the spring and clutch block are installed within the clutch block groove. The spring, clutch block, and shaft fork are in sequential contact. The latch plate is linked to the shaft fork, and the clutch block pull plate has a locking position, with the latch plate dynamically engaging with the locking position. The clutch block is in dynamic contact with the lever plate.

[0006] Furthermore, a protruding lever is provided on the clutch block pull plate for moving the linkage component.

[0007] Furthermore, the clutch block groove is a straight groove, with one end of the groove open for the clutch block to enter and exit, and the other end of the groove closed. A spring mounting column is set inside the groove along the groove axis, and the spring mounting column is connected to the closed end of the groove. Limit blocks are set on the groove wall.

[0008] Furthermore, the clutch block includes a groove mounting part, a rotation limiting part, and a movement limiting part; a latch extends outward from the groove mounting part and is used to contact the shaft core shift fork; the rotation limiting part is connected to the groove mounting part, and the movement limiting part is connected to the rotation limiting part and is used to cooperate with the groove limiting block.

[0009] Furthermore, the pivot fork includes a pivot body and a fork portion disposed outside the pivot body. The pivot body is used for linkage connection with the lock cylinder assembly, and the fork portion is used for contact with the clutch block.

[0010] Furthermore, the connecting plate is linked to the steel bar.

[0011] Furthermore, when the RV lock clutch assembly is in the disengaged state, the latch plate is inserted into the clutch block pull plate slot, the clutch block and the lever plate are not in contact, and the clutch block pull plate cannot move; when the RV lock clutch assembly is in the engaged state, the latch plate disengages from the clutch block pull plate slot, the clutch block and the lever plate are in contact, and the clutch block pull plate can move.

[0012] The beneficial effects of this application are as follows:

[0013] The clutch assembly is located between the handle and the latch linkage mechanism. It cuts off or transmits the external force from the inner or outer handle to the latch linkage mechanism. Therefore, when the lock is engaged, disengaging the clutch assembly cuts off the external force transmitted from the inner or outer handle to the latch linkage mechanism, preventing accidental handle activation and the lock from being opened while driving. To unlock, the clutch assembly must first be switched to the engaged position to reconnect the power transmission line from the inner or outer handle to the latch linkage mechanism. Then, turning the inner or outer handle will unlock the lock. This clutch assembly provides a double-locking function, ensuring lock security. Attached Figure Description

[0029] Furthermore, the terms "first," "second," etc., used in the specification and claims are used only for clarity of description to distinguish between different objects, and do not limit the size or other order of the objects they describe.

[0030] A type of RV lock, such as Figure 1 , Figure 2 As shown, it includes a locking unit 4, a central control unit 3, an outer handle unit 1, and an inner handle unit 2; the central control unit 3 is provided with locking units 4 at both the top and bottom ends, and the inner handle unit 2 and the outer handle unit 1 are provided on the inner and outer sides of the central control unit 3 respectively.

[0031] 1. External handle unit 1.

[0032] External handle unit 1 includes

[0033] The outer handle 11 is used to drive the clutch assembly 35 to move as a whole in the closed state. The outer handle 11 is set on the outer panel 14 on the outer surface of the central control unit 3 and is hinged to the outer panel 14. The outer handle 11 is linked to the clutch assembly 35 through the outer handle linkage assembly 12.

[0034] External handle linkage component 12 is used to link external handle 11 and clutch component 35.

[0035] The lock cylinder assembly 13 is used to switch the closed or open state of the clutch assembly 35; the lock cylinder assembly 13 is disposed on the outer panel 14 and is linked to the clutch assembly 35.

[0036] II. Inner handle unit 2.

[0037] The inner handle unit 2 includes

[0038] The inner handle 21 is used to drive the clutch assembly 35 to move as a whole in the closed state. The inner handle 21 is set on the inner panel 22 on the inner surface of the central control unit 3 and is hinged to the inner panel 22. The inner handle 21 is linked to the clutch assembly 35 through the inner handle linkage assembly 32.

[0039] Safety knob 23 is used to switch the clutch assembly 35 between closed and open states; safety knob 23 is located on inner panel 22 and is linked to clutch assembly 35 via safety knob linkage assembly 33.

[0040] III. Central Control Unit 3.

[0041] Central control unit 3 includes

[0042] The substrate 31 is used for component mounting, and the substrate 31 is an integrated plastic part structure;

[0043] The inner handle linkage component 32 is used to link the inner handle 21 and the clutch component 35.

[0044] Safety knob linkage assembly 33 is linked to safety knob 23 and clutch assembly 35;

[0045] Motor 34 is used to switch the engagement or disengagement state of clutch assembly 35; motor 34 is linked to clutch assembly 35.

[0046] Clutch assembly 35 is used to cut off or transmit the external force transmitted from inner handle 21 or outer handle 11 to latch linkage assembly 36;

[0047] The locking linkage component 36 is linked to the locking unit 4 and is used to drive the movement of the locking unit 4.

[0048] IV. Locking Unit 4.

[0049] The latch unit 4 and the lock lug 5 work together to open and close the lock. The latch unit 4 and the latch unit 5 are linked together.

[0050] In summary: When unlocking, the clutch assembly 35 must first be switched to the closed state by the lock cylinder assembly 13, safety knob 23 or motor 34, and then the clutch assembly 35 in the closed state is driven by the inner handle 21 or outer handle 11. The clutch assembly 35 in the closed state drives the latch linkage assembly 36, and finally opens the latch unit 4.

[0051] The state switching control route of clutch assembly 35 is as follows:

[0052] Lock cylinder assembly 13 — clutch assembly 35 (opening / closing state switching);

[0053] Safety knob 23 — Safety knob linkage assembly 33 — Clutch assembly 35 (disengagement / engagement state switching);

[0054] Motor 34 — Clutch assembly 35 (disengagement / engagement state switching);

[0055] The control route for latch unit 4 is as follows:

[0056] Inner handle 21—Inner handle linkage assembly 32—Clutch assembly 35 (closed state)—Lock linkage assembly 36—Lock unit 4;

[0057] External handle 11—External handle linkage assembly 12—Clutch assembly 35 (closed state)—Lock linkage assembly 36—Lock unit 4.

[0058] V. Specific structure and connection method of each unit component.

[0059] 1. The structure of the lock cylinder assembly 13 and the connection method between the lock cylinder assembly 13 and the clutch assembly 35.

[0060] The lock cylinder assembly 13 is connected to the shaft fork 352 in the clutch assembly 35. For example... Figure 7 As shown, when the lock cylinder assembly 13 is rotated to the unlock position, the shaft fork 352 is connected and rotated to the unlock state, ultimately causing the clutch assembly 35 to be in the closed state; as Figure 4 As shown, when the lock cylinder assembly 13 is rotated to the locked position, the shaft fork 352 is connected to rotate to the locked state, ultimately causing the clutch assembly 35 to be in the disengaged state.

[0061] 2. The structure of the safety knob linkage component 33, and the connection method between the safety knob linkage component 33, the safety knob 23, and the clutch component 35.

[0062] like Figure 4 , 6 As shown in Figures 7 and 9, the safety knob linkage assembly 33 includes a connecting shaft 331, a crank arm plate 332, and a straight pull plate 333 connected in sequence; wherein the safety knob 23 is connected to the connecting shaft 331, and the straight pull plate 333 is connected to the latch pull plate 351 in the clutch assembly 35; when the safety knob 23 is rotated to the unlock position, the safety knob linkage assembly 33 drives the latch pull plate 351, ultimately causing the clutch assembly 35 to be in the closed state; when the safety knob 23 is rotated to the lock position, the safety knob linkage assembly 33 drives the latch pull plate 351 to move, ultimately causing the clutch assembly 35 to be in the disengaged state.

[0063] 3. Connection method between motor 34 and clutch assembly 35.

[0064] like Figure 10As shown, the output shaft of motor 34 is connected to the latch plate 351 in clutch assembly 35. The output shaft of motor 34 performs linear extension and retraction. When motor 34 receives an unlocking command and extends, latch plate 351 moves synchronously in the forward direction, ultimately bringing clutch assembly 35 into the closed state. When motor 34 receives a locking command and retracts, latch plate 351 moves synchronously in the reverse direction, ultimately bringing clutch assembly 35 into the disengaged state.

[0065] 4. The structure of clutch assembly 35 and the clutch engagement / disengagement state of clutch assembly 35.

[0066] like Figure 3 As shown, the clutch assembly 35 includes a latch plate 351, a shaft fork 352, a clutch block pull plate 353, a clutch block 354, and a spring 355.

[0067] (1) Clutch block pull plate 353.

[0068] A clutch block groove 3531 is provided on the inner surface of the clutch block pull plate 353. The clutch block groove 3531 is a straight groove. One end of the groove 3531 is open for the clutch block 354 to enter and exit, and the other end of the groove 3531 is closed. A spring 355 mounting post 35311 is provided in the groove 3531 along the axis of the groove 3531. The spring 355 mounting post 35311 is connected to the closed end of the groove 3531. A limit block 35312 is provided on the groove wall of the groove 3531.

[0069] A protruding lever 3532 is provided on the outer surface of the clutch block pull plate 353, which is used to cooperate with the outer handle linkage assembly 12 and the locking linkage assembly 36, to receive the power of the outer handle linkage assembly 12, and at the same time press the locking linkage assembly 36 to move.

[0070] The clutch block pull plate 353 is provided with a locking position 3533 for dynamic engagement with the latch pull plate 351.

[0071] (2) Clutch block 354.

[0072] The clutch block 354 includes a groove mounting part 3541, a rotation limiting part 3542, and a movement limiting part 3543. A latch 3544 is provided extending outward from one axial end of the groove mounting part 3541. The rotation limiting part 3542 is connected to the groove mounting part 3541, and the movement limiting part 3543 is connected to the rotation limiting part 3542. The rotation limiting part 3542 is used to dynamically contact the steel bar connecting plate 323 in the inner handle linkage assembly 32.

[0073] (3) Shaft core shift fork 352.

[0074] The shaft fork 352 includes a shaft body 3522 and a fork portion 3521 disposed outside the shaft body 3522. The shaft body 3522 is used to be linked with the lock cylinder assembly 13, and the rotation of the shaft fork 352 is controlled by the lock cylinder assembly 13.

[0075] like Figure 4 , Figure 5 As shown, spring 355 is installed in clutch block groove 3531, and spring 355 is sleeved on the outside of spring 355 mounting post 35311. One end of spring 355 abuts against the closed end of groove 3531, and the other end of spring 355 contacts clutch block 354. Clutch block 354 groove mounting part 3541 is installed in groove 3531, rotation limiting part 3542 protrudes outside groove 3531, and movement limiting part 3543 is in contact with the groove. The limiting block 35312 in body 3531 dynamically engages, the shaft core fork 352 is hinged to the base plate 31, and the latch 3544 of clutch block 354 contacts the fork portion 3521 of shaft core fork 352; the spring 355 provides a thrust to clutch block 354, pushing clutch block 354 to move within groove 3531, pushing clutch block 354 from position G (closed position) to position H (disengaged position) within groove 3531, such as... Figure 4 , Figure 5 As shown, the latch 3544 of the clutch block 354 enters and exits from the open end of the slot 3531; as Figure 7 , Figure 8 As shown, the shaft fork 352 provides a thrust to the clutch block 354 in the opposite direction to the compression spring 355, which can move the clutch block 354 from the H position (disengaged position) to the G position (closed position) in the groove 3531.

[0076] like Figure 6 , 9 As shown, the latch plate 351 is linked to the safety knob linkage assembly 33, and the latch plate 351 is also hinged to the shaft fork 352. The latch plate 351 moves linearly; therefore, the safety knob linkage assembly 33 drives the latch plate 351 to move, which in turn drives the shaft fork 352 to rotate. Similarly, the rotation of the shaft fork 352 drives the latch plate 351 to move. As the latch plate 351 moves, one end K of the latch plate 351 dynamically engages with the locking position 3533 on the clutch block pull plate 353.

[0077] Clutch assembly 35 in disengaged state: such as Figure 4 , 5As shown in Figure 6, when the shaft fork 352 rotates in the opposite direction to the locked position by a certain angle, the spring 355 pushes the clutch block 354 from position G to position H (disengaged position). The clutch block 354 separates from the steel bar connecting plate 323 in the inner handle linkage assembly 32. When the steel bar connecting plate 323 rotates, it cannot apply pressure to the clutch block 354, and the power applied by the inner handle 21 is cut off, thus cutting off the power route of the inner handle 21. When the shaft fork 352 rotates in the opposite direction to the locked position, the latch plate 351 moves in the opposite direction simultaneously. The end K of the latch plate 351 is inserted into the locking position 3533 on the clutch block pull plate 353. The clutch block pull plate 353 cannot move in the L direction, and the clutch block pull plate 353 is locked. The clutch assembly 35 cannot be moved by the outer handle 11, and the power route of the outer handle 11 is cut off.

[0078] Clutch assembly 35 in the engaged state: such as Figure 7 , 8 As shown in Figure 9, when the shaft fork 352 rotates forward at a certain angle to the unlock position, the fork presses the clutch block 354 into the clutch block groove 3531, and the clutch block 354 is in position G (closed position). At this time, the rotation limit part 3542 of the clutch block 354 contacts the steel bar connecting plate 323 in the inner handle linkage assembly 32. The steel bar connecting plate 323 can rotate to apply pressure to the clutch block 354, and the power applied by the inner handle 21 can be transmitted, and the power path of the inner handle 21 is restored. When the shaft fork 352 rotates forward at a certain angle to the unlock position, the latch plate 351 moves forward synchronously, and the end K of the latch plate 351 disengages from the locking position 3533 on the clutch block pull plate 353. Then the clutch block pull plate 353 can move in the L direction, and the clutch assembly 35 can be moved by the outer handle 11, and the power path of the outer handle 11 is restored.

[0079] The pivot fork 352 in the clutch assembly 35 is linked to the lock cylinder assembly 13, such as... Figure 10 The clutch assembly 35's shaft fork 352 is also linked to the motor 34, and the clutch assembly 35's shaft fork 352 is also linked to the safety knob 23 through the safety knob linkage assembly 33; therefore, the shaft fork 352 can be rotated by the lock cylinder assembly 13, the motor 34, or the safety knob 23.

[0080] 5. The structure of the inner handle linkage component 32, and the connection method between the inner handle linkage component 32, the inner handle 21, and the clutch component 35.

[0081] like Figure 10As shown, the inner handle linkage assembly 32 includes an inner handle connecting pull plate 321, a No. 3 steel bar 322, and a steel bar connecting lever 323. The lever on the back of the inner handle 21 is inserted into a hole on the inner handle connecting pull plate 321 to achieve linkage connection between the two. One end of the No. 3 steel bar 322 is hinged to the steel bar connecting lever 323, and the other end is hinged to the inner handle connecting pull plate 321. The steel bar connecting lever 323 is in dynamic contact with the clutch assembly 35, and is hinged to the base plate 31. A point on the outer peripheral surface of the steel bar connecting lever 323 is in dynamic contact with the rotation limiting part 3542 of the clutch block 354.

[0082] The linkage process of inner handle 21—inner handle connecting plate 321—clutch assembly 35:

[0083] When the clutch assembly 35 is engaged, the clutch block 354 is in position G (engaged position). The rotation limit part 3542 of the clutch block 354 contacts the steel bar connecting plate 323, pulling the inner handle 21 and causing the inner handle linkage assembly 32 to move. At this time, the rotating steel bar connecting plate 323 in the inner handle linkage assembly 32 applies pressure to the clutch block 354, and the clutch block pull plate 353 moves along the L direction through the clutch block 354. The subsequent locking linkage assembly 36 and locking unit 4 are driven to move one by one, and the lock is opened.

[0084] When the clutch assembly 35 is disengaged, the clutch block 354 is in the H position (disengaged position). The rotation limit part 3542 of the clutch block 354 is not in contact with the steel bar connecting plate 323. Pulling the inner handle 21 causes the inner handle linkage assembly 32 to move. At this time, the rotating steel bar connecting plate 323 in the inner handle linkage assembly 32 cannot apply pressure to the clutch block 354 and cannot drive the clutch block pull plate 353 to move along the L direction. The subsequent locking linkage assembly 36 and locking unit 4 cannot be driven to move one by one, and the lock cannot be opened. That is, when the clutch assembly 35 is disengaged, the inner handle 21 can still be pulled, and the movement of the inner handle 21 itself is unrestricted, but it does not drive the locking unit 4 to move, which is a kind of virtual stroke.

[0085] 6. Connection method between the external handle linkage component 12, the external handle 11, and the clutch component 35.

[0086] like Figure 10 As shown, the external handle linkage assembly 12 is connected to the protruding lever 3532 on the clutch block pull plate 353 in the clutch assembly 35.

[0087] The linkage process of outer handle 11—outer handle linkage assembly 12—clutch assembly 35:

[0088] When the clutch assembly 35 is engaged, the clutch block pull plate 353 can move freely along the L direction. When the outer handle 11 is pulled outward, the outer handle linkage assembly 12 applies pressure to the protruding lever 3532 of the clutch block pull plate 353, causing the clutch block pull plate 353 to move along the L direction. The subsequent locking linkage assembly 36 and locking unit 4 are driven to move one by one, and the lock is opened.

[0089] When the clutch assembly 35 is disengaged, the clutch block pull plate 353 is restricted from moving along the L direction. When the outer handle 11 is pulled outward, the outer handle linkage assembly 12 applies pressure to the protruding lever 3532 of the clutch block pull plate 353, which cannot drive the clutch block pull plate 353 to move along the L direction. The subsequent latch linkage assembly 36 and latch unit 4 cannot be driven to move one by one, and the lock cannot be opened.

[0090] 7. Locking linkage component 36 structure.

[0091] like Figure 10 As shown, the locking linkage assembly 36 includes a first pull plate 361, a second pull plate 362, a first locking steel bar 363, and a second locking steel bar 364. The first pull plate 361 is hinged to the base plate 31, forming hinge point A; the first pull plate 361 is hinged to the first locking steel bar 363, forming hinge point B; the second pull plate 362 is hinged to the base plate 31, forming hinge point C; the second pull plate 362 is hinged to the second locking steel bar 364, forming hinge point D; and the first pull plate 361 and the second pull plate 362 are hinged to form hinge point E. The first locking steel bar 363 is connected to the first locking unit 4, and the second locking steel bar 364 is connected to the second locking unit 4.

[0092] Unlocking process: Apply external force to hinge point E of pull plate 361, pull plate 362, or both, causing pull plate 361 to rotate around hinge point A, which in turn causes hinge point B of pull plate 361 to rotate synchronously, and the first locking bar 363 is pulled towards the central control unit 3; similarly, pull plate 362 rotates around hinge point C, which in turn causes hinge point D of pull plate 362 to rotate synchronously, and the second locking bar 364 is pulled towards the central control unit 3, and the locking linkage assembly 36 is in the unlocked state.

[0093] 8. Connection method between locking linkage component 36 and clutch component 35.

[0094] like Figure 10 As shown, a protruding lever 3532 is provided on the outer surface of the clutch block pull plate 353 in the clutch assembly 35. The lever 3532 is located between the first pull plate 361 and the second pull plate 362 in the locking linkage assembly 36. The lever 3532 is used to apply external force to the hinge point E of the first pull plate 361, the second pull plate 362, or both.

[0095] When the clutch assembly 35 is in the closed state, the clutch block pull plate 353 is in the active state. The clutch block pull plate 353 can move along the L direction, pulling the inner handle 21 or the outer handle 11. The external force is transmitted to the clutch assembly 35 through the inner handle linkage assembly 32 or the outer handle linkage assembly 12. The clutch block pull plate 353 moves along the L direction. The lever 3532 on the outer surface of the clutch block pull plate 353 moves the latch linkage assembly 36. The first latch steel bar 363 and the second latch steel bar 364 are pulled. The latch plate 45 in the latch linkage assembly 36 disengages from the lock lug 5, and the lock is in the unlocked state.

[0096] VI. Lock unlocking process.

[0097] The first step is to switch the clutch assembly 35 to the closed state via the lock cylinder assembly 13, the safety knob 23, or the motor 34.

[0098] The second step is to drive the clutch assembly 35 to move by moving the inner handle 21 or the outer handle 11, which in turn drives the locking linkage assembly 36 to unlock the locking unit 4.

[0099] Unless otherwise specified in this specification, all techniques described herein are conventional techniques in the field.

[0100] The above are preferred embodiments of the present invention. Any other simple substitutions and modifications made under the premise of the present invention should be considered as falling within the protection scope of the present invention.
