Description

Technical Field

[0001] The invention relates to an internal control locking mechanism of an automobile, in particular to a locking, unlocking and opening mechanism for an automobile. Background Art

[0002] With the upgrading of automobile industry technology in recent years, more and more vehicles are seeking an opening mechanism that can maintain the open position after opening until it is manually reset. For example, the unlocking of the gearbox locking device of some cars' electronic shifting requires the opening mechanism to have its own stroke control to assist the gearbox unlocking and maintain the stroke. However, since the maximum stroke of the existing opening mechanism is fixed, it is necessary to reserve excess margin to ensure normal locking or unlocking, which causes the lock gap to be too large, affecting the locking effect; at the same time, due to factors such as lock manufacturing deviation, the lock stroke also has deviations, resulting in the opening mechanism often failing to open normally, and when developing locks with different stroke requirements, the opening mechanism needs to be redeveloped, which is time-consuming and labor-intensive, and increases the development cycle, development costs, and product costs. Summary of the invention

[0005] The operating handle is fan-shaped, and is hinged to the second pin shaft at the central angle of the fan. The shift block is arranged in the middle of the circular arc edge of the fan, and the limiting notch is arranged at the lower end of the circular arc edge of the fan.

[0006] A mounting seat is provided at the upper end of the operating handle, and a first mounting hole is provided at the upper end of the mounting seat for fixedly connecting with the upper end of the travel compensation tension spring.

[0008] The locking block is a mouse-shaped locking block, the mouse head at the upper end of the locking block corresponds to the limiting notch of the operating handle, a strip hole is provided in the center of the locking block, the first pin shaft is hinged in the strip hole, the long axis of the strip hole extends up and down, and a second mounting hole fixedly connected to a tension spring is provided on the side of the locking block facing the operating handle, and a laterally extending driving arm is provided at the mouse tail position at the lower end of the locking block, and the driving arm corresponds to the movement path of the shift block on the operating handle.

[0009] The upper and lower parts of the driving arm are both provided with guiding arc surfaces.

[0010] The surface of the shift block used for contacting the upper end surface of the driving arm is an arc surface, and the surface used for contacting the lower end surface of the driving arm is a plane.

[0011] The stored force of the extension spring is smaller than the stored force of the torsion spring.

[0012] The lower end of the base is provided with a through hole for the control cable to pass through.

[0013] The above-mentioned technical scheme is adopted: it includes an operating handle, a base, a locking block, and a tension spring. One side of the base is hinged to the locking block through a first pin shaft, and the other side is hinged to the fixed end of the operating handle through a second pin shaft. The side is fixedly connected to one end of the tension spring, and the other end of the tension spring is eccentrically connected to the locking block. A torsion spring is sleeved on the second pin shaft, one end of the torsion spring is fixedly connected to the operating handle, and the other end is fixedly connected to the base. A limiting notch is provided at the lower end of one side of the free end of the operating handle, and a shift block corresponding to the locking block is provided in the middle. It also includes an execution handle, the fixed end of the execution handle is hinged on the second pin shaft, the free end of the execution handle is used to connect the control cable, and the free end of the execution handle is connected to the free end of the operating handle through a stroke compensation tension spring, and the initial tension of the stroke compensation tension spring is greater than the maximum unlocking force of the lock.

The stroke of the operating handle is greater than the stroke of the lock. Since the initial tension of the stroke compensation spring is greater than the maximum unlocking force of the lock, during the opening action, the operating handle first drives the actuator handle to rotate synchronously through the stroke compensation spring, and the actuator handle stops rotating after reaching the open position of the lock. The operating handle can continue to rotate until it is locked by the locking block, so that the normal opening, unlocking or locking of the lock can be guaranteed without reserving excess margin, avoiding excessive gap of the lock controlled by the stroke, and the locking effect is good; at the same time, even if there is a deviation in the manufacturing of the lock causing the stroke of the lock to deviate, the stroke can be compensated by the stroke compensation spring to complete the opening, unlocking or locking of the lock, and when developing locks with different stroke requirements, the opening mechanism can be used without redevelopment, saving time and money costs.

[0014] The operating handle is fan-shaped, and is hinged to the second pin shaft at the central angle of the fan. The shift block is arranged in the middle of the circular arc edge of the fan, and the limiting notch is arranged at the lower end of the circular arc edge of the fan, which is used to limit and lock the locking block.

[0015] A mounting seat is provided at the upper end of the operating handle, and a first mounting hole is provided at the upper end of the mounting seat for fixedly connecting with the upper end of the travel compensation tension spring.

[0017] The locking block is a mouse-shaped locking block, and the mouse head at the upper end of the locking block corresponds to the limiting notch of the operating handle. The mouse head of the locking block is stuck in the limiting notch of the operating handle to form a lock; a strip hole is provided in the center of the locking block, and the first pin shaft is hinged in the strip hole. The position of the first pin shaft in the strip hole can change with the action of the opening mechanism, and the long axis of the strip hole extends up and down. A second mounting hole fixedly connected to a tension spring is provided on the side of the locking block facing the operating handle, and a laterally extending driving arm is provided at the mouse tail position at the lower end of the locking block. The driving arm corresponds to the movement path of the shift block on the operating handle, and the upper and lower parts of the driving arm are provided with guide arc surfaces. When the operating handle moves, the guide arc surface of the driving arm is pushed by the shift block to complete the unlocking or resetting action of the opening mechanism.

[0018] The surface of the shift block used for contacting the upper end surface of the driving arm is an arc surface, so that the shift block can shift the driving arm more easily during resetting; the surface used for contacting the lower end surface of the driving arm is a plane.

[0019] The stored force of the tension spring is smaller than that of the torsion spring, so that the shifting block can have enough force to push the locking block when the operating handle is reset.

[0029] The locking, unlocking and opening mechanism for the vehicle of the present invention takes the unlocking of the P gear of the automobile gearbox as an example:

[0030] See also Figure 1-Figure 8A locking, unlocking and opening mechanism for a vehicle comprises an operating handle 1, a base 2, a locking block 3 and a tension spring 4. One side of the base 2 is hinged to the locking block 3 through a first pin 5. A strip hole 18 is provided at the center of the locking block 3. The first pin 5 is hinged in the strip hole 18. The position of the first pin 5 in the strip hole 18 can change with the action of the opening mechanism. The long axis of the strip hole 18 extends up and down. The other side of the base 2 is hinged to the fixed end of the operating handle 1 through a second pin 6. The second pin 6 is fixedly connected to one end of the tension spring 4. The other end of the extension spring 4 is eccentrically connected to the locking block 3. A torsion spring 7 is sleeved on the second pin shaft 6. One end of the torsion spring 7 is fixedly connected to the operating handle 1, and the other end is fixedly connected to the base 2. A limiting notch 8 is provided at the lower end of one side of the free end of the operating handle 1, and a shifting block 9 corresponding to the locking block 3 is provided in the middle. The operating handle 1 is fan-shaped, and the operating handle 1 is hinged to the second pin shaft 6 at the central angle of the fan. The shifting block 9 is set in the middle of the circular arc edge of the fan, and the limiting notch 8 is set at the lower end of the circular arc edge of the fan, which is used to limit and lock the locking block 3. It also includes an execution handle 10, the fixed end of which is hinged on the second pin shaft 6, and the free end of the execution handle 10 is used to connect the control cable 11. The lower end of the base 2 is provided with a through hole for the control cable 11 to pass through. The free end of the actuating handle 10 is connected to the free end of the operating handle 1 through a travel compensation tension spring 12. The free end of the actuating handle 10 is provided with a mounting groove 16 for mounting the control cable 11, and the actuating handle 10 is connected to the lock through the control cable 11. The upper side of the free end of the actuating handle 10 is provided with a mounting bracket 17 for connecting with the lower end of the travel compensation tension spring 12, so as to realize travel compensation. The fixed end of the actuating handle 10 is provided with a hinge hole for hinged connection with the second pin 6, so that the actuating handle 10 can rotate around the second pin 6. The upper end of the operating handle 1 is provided with a mounting seat 13, and the upper end of the mounting seat 13 is provided with a first mounting hole 15 for fixed connection with the upper end of the travel compensation tension spring 12. The lower part of the mounting seat 13 is provided with an opening 14 for making way for the travel compensation tension spring 12 to avoid interference with the travel compensation tension spring 12. The mounting seat 13 of this embodiment is trapezoidal, the first mounting hole 15 is arranged at the upper bottom of the trapezoid, and the opening 14 is arranged at the lower bottom of the trapezoid. The actuating handle 10 is located below the opening 14. The initial tension of the travel compensation tension spring 12 is greater than the maximum unlocking force of the lock, and the stored force of the extension spring 4 is less than the stored force of the torsion spring 7, so that the shift block 9 can have enough force to push the locking block 3 when the operating handle 1 is reset.A second mounting hole 20 fixedly connected to the tension spring 4 is provided on the side of the locking block 3 facing the operating handle 1. The locking block 3 is a mouse-shaped locking block. The mouse head at the upper end of the locking block 3 corresponds to the limiting notch 8 of the operating handle 1. The mouse head of the locking block 3 is inserted into the limiting notch 8 of the operating handle 1 to form a lock; a limiting arm 22 extends from the upper part of the locking block 3 away from the operating handle 1, which can form a limit with the base 2; a laterally extending driving arm 19 is provided at the mouse tail position at the lower end of the locking block 3, and the driving arm 19 corresponds to the movement path of the shift block 9 on the operating handle 1. The upper and lower parts of the driving arm 19 are provided with guide arc surfaces 21. When the operating handle 1 moves, the guide arc surface 21 of the driving arm 19 is pushed by the shift block 9 to complete the unlocking or resetting action of the opening mechanism. The surface of the shift block 9 that contacts the upper end surface of the driving arm 19 is an arc surface, so that it is easier for the shift block 9 to shift the driving arm 19 during resetting; the surface that contacts the lower end surface of the driving arm 19 is a plane. Such a vehicle lock unlocking and opening mechanism can be maintained in the open position after opening until it is manually reset; with the design of the execution handle 10 and the stroke compensation tension spring 12, the execution handle 10 controls the lock through the control cable 11, and the operating handle 1 is connected to the execution handle 10 through the stroke compensation tension spring 12. The stroke of the operating handle 1 is greater than the stroke of the lock. Since the initial tension of the stroke compensation tension spring 12 is greater than the maximum unlocking force of the lock, during the opening action, the operating handle 1 first drives the execution handle 10 to rotate synchronously through the stroke compensation tension spring 12, and waits until it reaches the lock. After the lock is in the open position, the execution handle 10 stops rotating, and the operating handle 1 can continue to rotate until it is locked by the locking block 3. In this way, there is no need to reserve extra margin to ensure the normal opening, unlocking or locking of the lock, avoiding the lock gap controlled by the stroke being too large, and the locking effect is good. At the same time, even if there is a deviation in the manufacturing of the lock causing the lock stroke to deviate, the stroke can be compensated by the stroke compensation tension spring 12 to complete the opening, unlocking or locking of the lock, and when developing locks with different stroke requirements, the opening mechanism can be used without redevelopment, saving time and money.

[0031] The process of opening and unlocking with the present invention is to pull the operating handle 1, and the operating handle 1 rotates while driving the executive handle 10 to rotate synchronously. The shifting block 9 of the operating handle 1 shifts the locking block 3, so that the first pin 5 moves to the lower end of the strip hole 18 on the locking block 3, and then the tension spring 4 pulls the locking block 3 to make the mouse head of the locking block 3 rotate toward the operating handle 1. After reaching the unlocking position of the lock, the executive handle 10 stops rotating, the operating handle 1 continues to rotate, and the stroke compensation tension spring 12 is stretched until the mouse head of the locking block 3 bounces into the limiting notch 8 of the operating handle 1 under the action of the tension spring 4 and maintains the locked state.

[0032] The resetting process of the present invention is to pull the operating handle 1 so that the mouse head of the locking block 3 is disengaged from the limiting notch 8 of the operating handle 1, and the first pin shaft 5 moves to the upper end of the strip hole 18 on the locking block 3. Under the action of the tension spring 4, the mouse head of the locking block 3 rotates away from the operating handle 1. At this time, the operating handle 1 is released, and the operating handle 1 returns to its original position under the action of the torsion spring 7. When the stroke compensation tension spring 12 is no longer in a stretched state, the execution handle 10 is subjected to the restoring force transmitted by the control cable 11 and begins to return to its original position until the shift block 9 of the operating handle 1 shifts the locking block 3 so that the locking block 3 gives way to the shift block 9, and the limiting arm 22 of the locking block 3 is limited by the base 2, and the operating handle 1 and the execution handle 10 return to their initial positions, and the limiting block on the operating handle 1 forms a limit with the base 2.
